Hi,
I need coordinate transformations from pixel space to real 3D space.
PDL::Transform is great for this kind of operations. I've got the two
vectors (and hence a 2x3) matrix, let's call it $tm, of the x and y axes.
Unfortunately, t_linear(m=>$tm) complains that the matrix is not square.
The docs explicitly say that this should work.
Tested on 2.079 and 2.100.
pdl> $tm=ones(3,2); # That would also scale
pdl> t_linear(matrix=>$tm);
Runtime error: lu_decomp requires a square (2D) PDL

It would be great to restore that feature.
