PDL::FFT - FFTs for PDL
!!!!!!!!!!!!!!!!!!!!!!!!!!WARNING!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! As of PDL-2.006_04, the direction of the FFT/IFFT has been reversed to match the usage in the FFTW library and the convention in use generally. !!!!!!!!!!!!!!!!!!!!!!!!!!WARNING!!!...

PDL::Slatec - PDL interface to the slatec numerical programming library
This module serves the dual purpose of providing an interface to parts of the slatec library and showing how to interface PDL to an external library. Using this library requires a fortran compiler; the source for the routines is provided for convenie...

PDL::ImageND - useful image processing in N dimensions
These routines act on PDLs as N-dimensional objects, not as broadcasted sets of 0-D or 1-D objects. The file is sort of a catch-all for broadly functional routines, most of which could legitimately be filed elsewhere (and probably will, one day). Ima...

PDL::Primitive - primitive operations for pdl
This module provides some primitive and useful functions defined using PDL::PP and able to use the new indexing tricks. See PDL::Indexing for how to use indices creatively. For explanation of the signature format, see PDL::PP....

PDL::Transform - Coordinate transforms, image warping, and N-D functions
PDL::Transform is a convenient way to represent coordinate transformations and resample images. It embodies functions mapping R^N -> R^M, both with and without inverses. Provision exists for parametrizing functions, and for composing them. You can us...

PDL::Filter::Linear - linear filtering for PDL
A wrapper for generic linear filters. Just for convenience. This should in the future use DataPresenter. Also, this class should at some point learn to do FFT whenever it is useful....

PDL::DSP::Fir::Simple - Simple interface to windowed sinc filters.
At present, this module provides one filtering routine. The main purpose is to provide an easy-to-use lowpass filter that only requires the user to provide the data and the cutoff frequency. However, the routines take options to give the user more co...
