Are Matrix and/or MatrixReal still being maintained ? I am looking for something to do matrix/vector operations for colour space conversions for a Tk app I am looking at. I was looking for something much simpler that Math::MatrixReal, but with overloading, e.g. to convert xyz and rgb space : my $xform = new Matrix [[a,b,c],[d,e,f],[g,h,i]]; my $xyz = $xform * [$r, $g , $b]; my $ixform = $xform->invert; my $rgb = $ixform * $xyz; My main issue with MatrixReal is not with the matrices but the vectors - it would be good to be able to use raw perl arrays as vectors as above. - it would be even better if returned 'vector' took account of context: my ($r,$g,$b ) = $ixform * $xyz; Is Math::Matrix up for additions or should I go for new class (say) Math::MatrixXform; -- Nick Ing-Simmons
