(For the exported PDL constructor, pdl(), see PDL::Core) PDL is the Perl Data Language, a perl extension that is designed for scientific and bulk numeric data processing and display. It extends perl's syntax and includes fully vectorized, multidimens...

Now that you have some idea how to use "pp_def" to define new PDL functions it is time to explain the general syntax of "pp_def". "pp_def" takes as arguments first the name of the function you are defining and then a hash list that can contain variou...

PDL contains many modules for displaying, loading, and saving data. * Perlish or Text-Based A few IO modules provide Perl-inspired capabilities. These are PDL::IO::Dumper and PDL::IO::Storable. PDL::IO::Misc provides simpler routines for dealing with...

This module provides the functions used by PDL to overload the basic mathematical operators ("+ - / *" etc.) and functions ("sin sqrt" etc.) It also includes the function "log10", which should be a perl function so that we can overload it! Matrix mul...

PDL has been compiled with WITH_BADVAL set to 1. Therefore, you can enter the wonderful world of bad value support in PDL. This module is loaded when you do "use PDL", "Use PDL::Lite" or "PDL::LiteF". Implementation details are given in PDL::BadValue...

A simple cookbook how to create piddles manually. It covers both the Perl and the C/XS level. Additionally, it describes the PDL core routines that can be accessed from other modules. These routines basically define the PDL API. If you need to access...

These packages implements a couple of functions that should come in handy when debugging your PDL scripts. They make a lot of sense while you're doing rapid prototyping of new PDL code, let's say inside the perldl or pdl2 shell....

This module explains how to get help with a PDL problem and how, when, and where to submit a bug report. In the future it may be extended to provide some sort of automated bug reporting capability....

This module extends PDL with more advanced mathematical functions than provided by standard Perl. All the functions have one input pdl, and one output, unless otherwise stated. Many of the functions are linked from the system maths library or the Cep...

Loads the smallest possible set of modules for PDL to work, importing only those functions always defined by PDL::Core) into the current namespace ("pdl", "piddle", "barf" and "null"). This is the absolute minimum set for PDL. Access to other functio...

This subclass of PDL allows one to manipulate PDLs of 'byte' type as if they were made of fixed length strings, not just numbers. This type of behavior is useful when you want to work with charactar grids. The indexing is done on a string level and n...
