Hi, I am trying to do complex matrix multiplication using PDL. I used an example from here, however, I get an error.

2x2 matrix *** this works fine **** #! /usr/bin/perl -w use warnings; use strict; use PDL; use PDL::Complex; my $matrixM = pdl [ [ 1+1*i, 2+1*i], [ 1-2*i, 2-1*i] ]; print "Via Perl Data Language\n"; print "List assigned_values of matrices:\n"; print "\$matrixM = ", $matrixM,"\n"; print "\n Inv of \$matrixM = ", $matrixM->inv,"\n"; print "\n\n+++++++++++++++++++++++++\n\n"; exit(0);

I just extended the matrix from 2x2 to a 3x3, I get an error "PDL: inverse needs a square PDL as a matrix"

3x3 matrix *** does not work **** #! /usr/bin/perl -w use warnings; use strict; use PDL; use PDL::Complex; my $matrixM = pdl [ [ 1+1*i, 2+1*i, 3+1*i], [ 1-2*i, 2-1*i, -2+1*i], [ -1+1*i, 2+1*i, -1+1*i] ]; print "Via Perl Data Language\n"; print "List assigned_values of matrices:\n"; print "\$matrixM = ", $matrixM,"\n"; print "\n Inv of \$matrixM = ", $matrixM->inv,"\n"; print "\n\n+++++++++++++++++++++++++\n\n"; exit(0);

Thanks in advance,

smh
