Internal module to handle signatures...

An implementation of online docs for PDL....

PDL::CCS is now just a wrapper package which pulls in a number of submodules. See the documentation of the respective modules for details....

!!!!!!!!!!!!!!!!!!!!!!!!!!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!!!...

Methods and functions for type conversions, PDL creation, type conversion, threading etc....

This module provides some primitive and useful functions defined using PDL::PP based on functionality of what are sometimes called *ufuncs* (for example NumPY and Mathematica talk about these). It collects all the functions generally used to "reduce"...

This package provides many of the powerful PerlDL core index manipulation routines. These routines mostly allow two-way data flow, so you can modify your data in the most convenient representation. For example, you can make a 1000x1000 unit matrix wi...

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...

Internal module - holds all the PDL Type info. The type info can be accessed easily using the "PDL::Type" object returned by the type method. Skip to the end of this document to find out how to change the set of types supported by PDL....

callext() loads in a shareable object (i.e. compiled code) using Perl's dynamic loader, calls the named function and passes a list of piddle arguments to it. It provides a reasonably portable way of doing this, including compiling the code with the r...

PDL::SVDLIBC provides a PDL interface to the SVDLIBC routines for singular value decomposition of large sparse matrices. SVDLIBC is available from http://tedlab.mit.edu/~dr/SVDLIBC/...

These routines act on PDLs as N-dimensional objects, not as threaded 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). ImageN...

Miscellaneous 2D image processing functions - for want of anywhere else to put them....

Collection of a few commonly used routines involved in handling of RGB, palette and grayscale images. Not much more than a start. Should be a good place to exercise some of the thread/map/clump PP stuff. Other stuff that should/could go here: * color...

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....

Slicing is a basic, extremely common operation, and PDL's slice method would be cumbersome to use in many cases. "PDL::NiceSlice" rectifies that by incorporating new slicing syntax directly into the language via a perl *source filter* (see the perlfi...
