### Minor changes

- cell arrays accepted by
`strmatch` `mpower`where the first operand is a square matrix and the second any scalar, not only a real integer- in
`sprintf`and other function for formatted output,`%x`and`%o`truncated numbers while`%d`rounded them; now all integer formats round numbers - anonymous functions without output argument, such as
`@(f) format(f)` - simplified syntax for indices in
`subsref`and`subsasgn` - indices and values returned by
`find`with option`'last'`not reversed anymore `median`gives`NaN`for vectors which contain`NaN`- in function
`latex2mathml`, new named argument`displaymath` - more character macros defined in
`latex2mathml` - horizontal space macros (
`\;`,`\quad`etc.) defined in`latex2mathml` `\begin{array}{...}`,`end{array}`and`\\`defined in`latex2mathml``\phantom{...}`defined in`latex2mathml`- named argument
`fd`in`fprintf`as an alternative to unnamed argument`fd` - documentation for
`householder`and`householderapply` - better LME source code parsing allowing function definitions not at the beginning of a line

### Bug fixes

`norm`1 or inf of non-square matrices fixed`join`without input argument fixed- nested assignment to struct fields could produce garbage; fixed
`arrayfun`didn't accept cell arrays; fixed`bitcmp(scalar,array)`fixed`care`sometimes produced nan results with valid inputs; fixed`base64decode`could produce garbage when the base64 sequence wasn't properly terminated; fixed- concatenation of struct arrays with different number of fields fixed

`f()`where`f`is a variable which contains a function reference or an anonymous function, fixed - functions without output arguments in anonymous functions used in larger expressions fixed
`bitall`and`bitany`fixed`hypot(0,0)`fixed- implicit argument name in
`inline`only with exactly one string argument; this permits anonymous functions without argument, such as`a=2; fun=@() a;` - anonymous functions with multiple output arguments fixed
- assignments to nested lists, cell arrays or structures, which gave sometimes incorrect results or crashes, fixed
`error`with a custom error identifier and no error message reused the previous error message; fixed`fwrite`with an invalid fd failed silently; now it throws an error- padding of formatted integer numbers fixed
`qr(A,false)`memory requirements, previously too high, fixed- option
`PreArg`fixed in`ode45`and`ode23` `info('u')`with an output argument returned a list with only the first used library; fixed

`@/base64` - definition of structs and n-by-1 struct arrays with braces and named values
`apply`with support for named arguments- named argument
`throwAsCaller`in`error`and`rethrow` - named argument
`NPrec`in`dumpvar` - in
`dbtype`, optional output argument to get function source code in a string - line breaks are ignored between brackets after a comma, which makes the three dot escape sequence superfluous there

### Minor changes

- display of cell arrays and structures improved
- first argument of
`optimset`,`odeset`, etc. can be an empty matrix to stand for the default options - with keywords,
`which`displays "(keyword)/..." `info s`gives also the size of double (8 bytes on all current platforms)`isa(x,'cell')`gives true if`x`is a list or a cell array`findstr`renamed`strfind`for the sake of consistency and compatibility with other applications- the profiler can be used with functions whose source code isn't available anymore (e.g. those defined from the command-line interface)
`dumpvar`made faster- for each library,

`fun`contained a function reference or an anonymous or inline function, it couldn't be called without input argument with the syntax`fun()`; fixed - in rare cases, anonymous functions with variable number of output arguments could not be compiled correctly and resulted in a syntax error; fixed
- anonymous functions without input argument but with captured variables failed; fixed
`odeset`option`EventTime`with fixed events could fail; fixed`help`and`lookfor`for functions defined in libraries which weren't loaded sometimes failed; fixed`var(indices)=[]`or`var(select)=[]`with a single value in parenthesis didn't always produce the correct result; fixed- anonymous function

`include`or`includeifexists`fixed `cond([])`produced garbage; fixed (gives 0)`cov`with complex data fixed- indexed element deletion of an undefined variable could lead to data corruption or crashes; fixed
- in
`fzero`, test to stop infinite range expansion (e.g. for`fzero(@(x)1,2)`)

### Windows

- extension functions with the same name as the dll file might cause a crash; fixed

## LME 5.1

### New features

- engineering format with
`format`,`fprintf`,`sprintf`and`bprintf` - line breaks are ignored between parenthesis and braces, which makes the three dot escape sequence superfluous in many cases
- anonymous functions can have multiple output arguments (when they have a top-level function call, the number of output arguments is passed from the caller)
- value sequences, a generalization of the
`v{:}`syntax (now any indexing expression(s) can be provided in the braces, and the resulting item(s) are used as if they were enumerated explicitly and separated with commas in function input arguments, matrix rows, lists, or cell array rows) `interp1`(1D interpolation)- option
`Past`in`odeset`to add past time and state values to ODE (useful to integrate delay differential equations) - structure arrays; new functions
`structarray`,`cell2struct`, and`struct2cell`; support in`beginning`,`cat`,`ctranspose`,`disp`,`dumpvar`,`end`,`flipdim`,`fliplr`,`flipud`,`horzcat`,`ipermute`,`isempty`,`length`,`ndims`,`permute`,`repmat`,`reshape`,`rot90`,`size`,`squeeze`,`transpose`,`vertcat`, and variable refererence and assignment - new built-in function
`factor`(was in library`stdlib`) `info s`(size of integers and pointers)

### Minor changes

`interpn`now supports any numerical data type and converts the result to double- when structures and lists are displayed, control chacters in strings are displayed as question marks
- support for
`fflush`with files - syntax
`f(...)`to evaluate a function reference or an inline or anonymous function stored in a variable`f`now supports multiple output arguments `classdef`is a new reserved keyword`apply`has now a limit of 256 output arguments if their number is not specified`horzcat`and`vertcat`accept any number of input arguments- in
`interpn`, optional argument for the extrapolated value - in
`ode23`and`ode45`, time step is reduced before events to improve their precision and reduce the risk of event repeating - with an output argument,
`info`,`inmem`, and`dbstack`return now a structure array instead of a list of structures

### Bug fixes

`interpn`with decreasing input coordinates could produce NaN when it shouldn't; fixed

## LME 5.0.1

### New features

`includeifexists`

### Minor changes

`fgets`and`fgetl`now return an empty string upon end-of-file, so that`while feof(fd)`can be used without error catching`interpn`check the size of input arguments before the coordinate monotonicity, to give a more informative error in case the result of`meshgrid`is given instead of vectors of coordinates- improved
`help`and`lookfor`: help for functions defined in libraries provided with Sysquake is available also before the library has been loaded with`use`

### Bug fixes

- when requesting more data than available,
`fread`gave an end-of-file error in text mode only; fixed - in the command-line interface, once an attempt to call a function
in a library was made before the library was imported, a subsequent
`use`statement didn't define the function in the correct context; fixed `ss2tf`numerator degree reduction could introduce dummy zeros which become apparent in some cases, such as magnitude frequency responses with loglog scale; fixed

## LME 5.0

### New features

- anonymous functions with captured variables and optional argument to inline functions for constant parameters
- new
`_pragma`directive, with`_pragma line`which changes the current line number (useful in code translated from another source file) - new function
`hypot` - support for styled text with fd=4
- styled text for help
- internal support to mark libraries from some sources as untrusted, so that their functions run in the sandbox
`info b`displays`u`after each untrusted function (functions which cannot be executed in the sandbox) and`L=info('b')`return the trusted flag for each function

### Bug fixes

- in some uncommon cases, index expressions in assignments with multiple
output arguments where the indexed array wasn't a variable weren't interpreted
correctly (e.g.
`(a,b)=size((1:10)(2:6))`threw an error) ; fixed - when built-in functions and operators permitted by
`str2obj`were overridden by an extension, their use became illegal; fixed

## LME 4.7.1

### Bug fixes

- element deletion along one of multiple dimensions with logical
selection, such as
`V(:,[false,true,false],:)=[]`, might corrupt variables; fixed `fft`whose argument length was a multiple of a prime number larger or equal to 31 was wrong; fixed

## LME 4.7

### New features

- in command syntax, arguments can be enclosed in single quotes; then spaces and escape sequences beginning with a backslash are interpreted like in normal quoted strings
- new functions
`inmem`,`goldenratio` - new functions
`meshgrid`and`ndgrid`(removed from library`stdlib`) - support for complex matrices in built-in versions of
`null`,`orth`and`pinv` - support for nonsymmetric and complex matrices in built-in version of
`eig`

### Minor changes

`(U,S,V)=svd(M,false)`removes not only`m-n`last columns of`U`if`m>n`, but also`n-m`last columns of`V`if`m<n`(to have the same behavior as before, write`svd(M,size(M,1)<size(M,2))`)`clc`with an optional file descriptor`format '+'`displays negative numbers as`-`and pure imaginary nonzero numbers as`I`

### Bug fixes

- when the last element of
`varargout`was an empty array, it was ignored; fixed `sort`and`unique`with complex matrices produced garbage; fixed- support for single type in
`sort` - support for single type in operator
`:` - assignments with a colon in the indices and incompatible dimensions of
the right-hand side expression, such as
`v=[]; v(:,1)=[1,2]`, could cause a crash; fixed - built-in version of
`orth`didn't always produce the correct result; fixed - in rare cases, built-in
`schur`, and functions which depend on it (`lyap`,`dlyap`,`care`, and`dare`), didn't converge (e.g.`schur([0,0,0,1;1,0,0,0;0,1,0,0;0,0,1,0])`); fixed `d1~=d2`, where`d1`and/or`d2`was complex, wasn't always correct; fixed- on platforms using Unicode,
`disp`didn't display correctly strings with characters code`>127`in list elements or structure fields; fixed - assignment
`v(...)=[]`, where`v`was undefined and indices contained at least one colon, corrupted variable data and could lead to a crash; fixed `fprintf`and`sprintf`, with format`%d`,`%i`,`%o`or`%x`, displayed finite numbers instead of`inf`,`-inf`or`nan`; fixed- literal strings beginning with characters between 0 and 127 followed by characters between 128 and 255 were corrupted; fixed

`strtok`

### Minor changes

`sinc(x)`is defined as`sin(pi*x)/(pi*x)`instead of`sin(x)/x``sum`,`prod`and`mean`now return an empty array for empty inputs when the`dim`parameter is specified- scalar operators with a scalar operand are faster
`findstr(s1,s2)`with an empty`s2`returns an empty array instead of`1:length(s1)+1`- integer and single numbers can be used as indices in array subscripts
- format
`%i`in`fscanf`and`sscanf`accept binary numbers prefixed by`0b`or`0B` - in
`ode23`and`ode45`, the time step is now reset when an event occurs to avoid an unlimited growing when the ode is integrated without error - operators
`/`and`\`throw error "Non-square matrix" instead of "Incompatible size" when the left or right operand is a non-square matrix, respectively

### Bug fixes

- in
`ode23`and`ode45`, events were missed if the`OnEvent`function provoked a change of sign of the value returned by the`Events`function; fixed `inline`without input argument produced undefined results instead of a clean error; fixed- in
`ode23`and`ode45`, events are disabled during the integration step following an event, to prevent shattering - matrix multiplication by empty matrix and division of empty matrix didn't always give an empty matrix; fixed

### Bug fixes

- spaces weren't supported between a list of variables in the left-hand side
of an assignment and the closing bracket (such as

### Minor changes

- execution speed has been improved
- to remove element(s) from a list or a cell array, the syntax
`listvar(index)=[]`is supported in addition to`listvar(index)={}`, for compatibility with Matlab - user breaks (with Control-C or its platoform-dependent equivalent) is not
caught by
`catch`anymore - global and persistent variables are now forbidden in code executed
by
`sandbox`(`sandboxtrust`can be used to circumvent this restriction) - the transpose operators (
`'`and`.'`) can be applied to any kind of arrays, not only 2-dim; dimensions 1 and 2 are permuted `fminbnd`and`fminsearch`with 2 or 3 output arguments- support for single-precision input arguments in
`min`,`max`,`sort`,`unique`,`find`, and`repmat` - support for all kinds and dimensions of numerical, char, and logical arrays in
`num2list` - new options
`'Priority'`and`'Sandbox'`in`threadset` - the second output argument of
`sort`for lists (and cell arrays) is now a row vector instead of a column vector, so that`S===L(I)`for`(S,I)=sort(L)` `x^2`, where`x`is a real scalar double, is implemented as`x*x`for faster execution and exact output when possible- option for ascending or descending direction in
`sort` - support for 2 or 3 input arguments in
`find`to limit the number of values found `find`preserves the type char or logical in the 3rd output argument to match the input type`find`generates an error with input arrays with more than 2 dimensions and 2 or 3 output arguments (`ind2sub`can be used to get the subscripts for arrays of any dimension)`care`with 5 input arguments- on platforms which use UTF-8, initial BOM (Byte-Ordering Mark) in libraries are ignored
`tril`,`triu`, and`diag`accept 2-d arrays of any numerical, logical or char class`beginning`can be defined as a variable or a function (then the built-in definition used in index expressions will be hidden)`fft`has been accelerated for real input`format`now accepts option`bank`for display with 2 fixed decimal digits, and format`'+'`for display of arrays with`+`for nonzero elements and spaces for zero elements- functions
`fprintf`,`sprintf`and`bprintf`support the format`%i`and the flag`#`

### Bug fixes

`end`in an index expression for a single-precision array variable returned an error; fixed`size`wth an empty array and multiple output arguments gave 1 for trailing (superfluous) dimensions instead of 0; fixed`v{ix}`where v was a structure was accepted; fixed`threadsleep`didn't always suspend threads correctly; fixed- on some platforms,
`ss2tf`with a single output argument crashed since LME 4.3; fixed `bitshift`with two input arguments, the first one being an integer, didn't produce the correct result; fixed`size(A,dim)`where`A`was empty and`dim>2`gave 1 instead of 0; fixed`funm([],fun)`,`sqrtm([])`, and`logm([])`gave an error; fixed (give`[]`, and 0 for the optional second output argument of`funm`)- the number of libraries was limited to 16 by context; now it's limited only by memory
- in assignments to subscripted lists where subscripts weren't in ascending
order, the assigned elements weren't in the correct order (for instance
`L([2,1])={20,10}`set the 2 leading elements of`L`to`20`and`10`); fixed `unique`didn't produce a row vector when the input was a row vector of a non-double type; fixed- dumping the state of LME cleared unused memory space, which was useless and forced memory allocation on systems with virtual memory; fixed
- there was no error message for unexpected
`else`; fixed - functions
`and`,`balance`,`chol`,`ctranspose`,`eig`,`eye`,`flipdim`,`fliplr`,`flipud`,`funm`,`hess`,`householder`,`householderapply`,`ind2sub`,`isscalar`,`isvector`,`kron`,`linprog`,`lu`,`ndims`,`ones`,`or`,`pinv`,`rand`,`randn`,`schur`,`str2fun`,`sub2ind`,`trace`,`transpose`,`tril`,`triu`,`unique`,`xor`, and`zeros`couldn't be overloaded; fixed - assignments like
`a(i,j)=[]`threw the error`Deleting elements along multiple dimensions`even when`i`and`j`selected 0 element because they were empty or false; fixed `lu`works now with singular and rectangular matrices`c2dm`with first-order hold and transfer function didn't always produce the correct numerator; fixed- with command syntax, spaces between the last argument and a semicolon or a
comma caused an empty string to be passed as an additional input argument
(e.g.
`disp a ;`was interpreted as`disp('a','')`); fixed - on platforms which supported it (Mac OS X and other unix), loading user extensions from several places didn't work correctly; fixed
- assignments like
`A(sel,...)=B`with multiple subscripts, where`sel`was a logical vector, didn't always produce the correct result; fixed `repmat`didn't copy elements correctly when the result was a column vector; fixed- number beginning with 08 or 09 were decoded as decimal; now they're considered as illegal octal
`dumpvar`with a negative file descriptor threw an out of memory error; now they throw an bad file descriptor error
