PDL::Slatec - PDL interface to the slatec numerical programming library River stage two • 90 direct dependents • 97 total dependents

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 River stage two • 90 direct dependents • 97 total dependents

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 River stage two • 90 direct dependents • 97 total dependents

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::DSP::Fir::Simple - Simple interface to windowed sinc filters. River stage one • 1 direct dependent • 1 total dependent

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...
