PDL-FFTW
========

This module provides bindings to the FFTW version 2.x library
(the original API).  It was originally part of the PDL distribution
As of Aug 2013, it has been spun off into its own distribution for
improved portability and to make way for FFTW3.


DEPENDENCIES

This module requires these other modules and libraries:

This module needs the perl PDL module and the FFTW library
version 2 installed.  FFTW is a free C FFT library including
multi-dimensional, real, and parallel transforms.
See http://www.fftw.org/ for the sources and directions
for how to build the module.

This module is not compatible with the current FFTW3 API.


CONFIGURATION OPTIONS

Please edit the fftw.conf file to change the configuration
options repeats from that file here for convenience:

   # Location to search for the FFTW libs, overrides default if defined
   FFTW_LIBS => undef,    # [ '/lib','/usr/lib','/usr/local/lib'],
   
   # Location to find FFTW includes, overrides default if defined
   FFTW_INC => undef,     # ['/usr/include/','/usr/local/include'],
   
   # FFTW Numeric Precision Type to link in: (double or single precision)
   FFTW_TYPE => 'double', # 'single'
