Hi,
Relevant code might work with matlab, but pdl has a different look while constructing matrices.
First you write dimension of columns, then rows, which is reverse of matlab and octave.
forexample, sequence(4,3) create a 3 x 4 matrix which should be confusing for a matlab user.
#!/usr/bin/perl
use PDL;
use PDL::Matrix;
$a = sequence(2,3);
$b = sequence(3,3);
$z= $a x $b;
print $z;
Error in inner:Wrong dims
Insert below snippet before $x = A x B x C x D;
print $A->getdim(0); #column
print $A->getdim(1); #row
....and for the rest matrices
May be you got confused of matrices of pdl.
Cheers
