C complex number usage

[Kevin D. Clark]

You might consider using Perl's Math::FFTW module for your problem:

Another module that you might find to be useful is Perl's
Math::Complex module:

  http://search.cpan.org/~nwclark/perl/lib/Math/Complex.pm

Or, depending on the size and scope of your problem, you might have to
code this in C and consider using something like MPI or MPICH.

Programming in C takes some work; making your solution code amenable
to running on some sort of a parallel computer takes a bunch more
work.  Depending on your problem size, this might be worth it (or
not).
