Hi there
I'm currently trying to get to grips with the PDL module .. i'm wanting to calculate the determinant for a 4x4 matrix. This is the code I've managed to create so far 
#!/usr/bin/perl -w

use strict;

use PDL::MatrixOps;

my $mat = pdl [
           [3.4603, 1.7529, 1.6990,2.1181],
           [ 2.5459,2.5615,2.2525,2.3606],
           [ 2.3606, 2.2515, 2.5628,2.5459],
           [ 2.1181,1.6982,1.7537,3.4603],
           ];

my $det = determinant($mat);

print "$det\n";

But it comes up with a syntax error 
syntax error at ./test.pl line 7, near "pdl ["
Execution of ./test.pl aborted due to compilation errors.

Any help much appreciated
