polynom: in polynom::roots, ratfun::isproper and ratfunzp
constructor, leading zero polynomial coefficients ignored
Bug fixes
polynom: in ratfunzp::char (and ratfunzp::disp which calls it),
inf and nan caused an infinite loop; fixed
lti: no more leading zero coefficients in transfer functions resulting from the conversion of pid
objects with zero parameters
LME 6.0.1
Bug fixes
lti: graphical functions have not accepted string style arguments since version 6.0; fixed
LME 6.0
New
lti: zpk, pid, pidstd and frd classes
lti_filter (new)
polynom (aka classes): ratfunzp class for rational functions
defined by zeros, poles and gain
Minor changes
stdib: isprime, linspace, logspace, and
median removed (built-in functions)
date: support for second fractions in datestr
classes.lml has been renamed polynom.lml, and a new classes.lml includes
polynom.lml for backward compatibility
sigenc.lml, filter.lml: unused arguments replaced with ~
Bug fixes
lti: tf::mpower actually computed tf::power; fixed
(both power and mpower are implemented)
polynom: operations where the first argument was a polynom and the second one
a ratfun failed; fixed thanks to superiorto
tf::minreal introduces less roundoff errors, especially when transfer functions
order cannot be reduced
LME 5.1
Minor changes
stdib: factor removed (built-in function)
LME 5.0
New
colormaps: color maps for colormap command
polyhedra: regular polyhedra
solids: simple solid shapes
LME 4.7
Minor changes
classes: in char and disp, support
for complex coefficients
classes: all errors have error identifiers
quaternion: not bundled anymore (replaced by native support of quaternions)
LME 4.6
New features
stdlib: ndgrid
Minor changes
stdlib: fft2, ifft2, std, and
cross have been removed (they are native now)
stat:
moment, var, skewness,
and kurtosis have been removed (they are native now)
bench: uint8 benchmark requires less memory for setup
(no effect on timings)
bench: new results for Intel Macintosh and Atari ST
Bug fixes
lti: zpk didn't pass correctly arguments to tf::tf;
fixed
stdlib: toeplitz with a single argument was broken;
fixed
LME 4.5.2
Minor changes
lti, quaternion, stdlib: prod(size(...)) replaced
by numel(...)
Bug fixes
lti: tf::horzcat and tf::vertcat didn't
work correctly with models without any state; fixed
lti: tf::connect was missing; fixed
LME 4.5.1
Minor changes
stdlib: functions sec, csc, cot,
asec, acsc, acot,
sech, csch, coth,
asech, acsch, acoth,
and log2 have been removed; they're now native in LME
Bug fixes
wav: glitch in the source code fixed
LME 4.5
New features
bench: new
date: new
stdlib: blkdiag
lti: ssdata, tfdata
lti: lti::norm (H2 norm)
lti: lti::isct, lti::isdt,
lti::dcgain
quaternion: support for matrices of quaternions; internal structure has
changed, double gives now an m-by-n-by-4 array, arithmetic
operators now work on quaternion matrices like on real or complex
matrices, inv and matrix division operators work on
matrices and not element-wise; new functions

Minor changes
lti: tf objects have a cell array of ratfun
objects instead of a list and a separate field for the size
lti: tf::feedback and tf::plus apply
minreal to the result to remove superfluous states
lti: ss::repmat
lti: tags for all error messages
lti: G*H and G+H, where G
or H is 1-by-1
lti: the sample time of lti objects representing static gains is ignored
in expresions where they would cause the error "Sample time don't match"
stdlib: logspace displays a warning when the upper bound
gives infinity
Bug fixes
stdlib: toeplitz(c,r) where length(r) was
1 gave c' instead of c; fixed
lti: lti::disp doesn't display a superfluous blank line
anymore
lti: tf::feedback for SISO systems ignored the sign
argument; fixed
lti: lti::feedback couldn't mix state-space, transfer
functions or numeric matrices; fixed
lti: tf with a sample time had a default variable name
of 's'; no it's 'z'
lti: ss::minreal didn't always produce the correct result;
fixed
