Hi, I'm having problems with PDL::FFTW. Perl says: Can't locate PDL/FFTW.pm in @INC (@INC contains: C:/Perl/site/lib C:/Perl/lib .) at E:\fftw\noname.pl line 6, <DATA> line 206. BEGIN failed--compilation aborted at E:\fftw\noname.pl line 6, <DATA> line 206. PDL is installed and working, see my code example:

# usr/bin bla
# Using FFTW for fractional calculus
use PDL;
use PDL::Complex;
use PDL::IO::Misc;
use PDL::FFTW;

$PDL::IO::Misc::colsep="\t";

$cols=2;
$rows=0;

    open (DATA_1, "data.dat") || die "File not found\n";
    $j=-1;
    while (<DATA_1>) {
    $j++;
    chomp($_);
    my @dummy=split(/\t/, $_);
    (@voltage[$j]) = @dummy[0]."\n";
    (@current[$j]) = @dummy[1]."\n";
    }
    close(DATA_1);

print @voltage;
print "\n\n";
print @current;
print "\n\n";
$pdlcurrent = pdl(@current);
print nelem ($pdlcurrent);
print "\n\n";
# until this point everything works fine
$fft_test = fftw ($pdlcurrent);

Any suggestions? Where do I get FFTW.pm from? It's not to be found in PDL directory!
