PDL - the Perl Data Language

42 ++

42 ++

(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...

PDL::Ops - Fundamental mathematical operators

42 ++

42 ++

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::Doc - support for PDL online documentation

An implementation of online docs for PDL....

PDL::Dbg - functions to support debugging of PDL scripts

42 ++

42 ++

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....

PDL::Core - fundamental PDL functionality and vectorization/threading

42 ++

42 ++

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

PDL::Lvalue - declare PDL lvalue subs

42 ++

42 ++

Declares a subset of PDL functions so that they can be used as lvalue subs. In particular, this allows simpler constructs such as $x->slice(',(0)') .= 1; instead of the clumsy (my $tmp = $x->slice(',(0)')) .= 1; This will only work if your perl suppo...

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

PDL::Bad - PDL always processes bad values

PDL::Dims - Enhancement to PDL by using named dimensions.

++

++

This module is an extension to PDL by giving the dimensions a meaningful name, values or ranges. The module also provides wrappers to perform most PDL operations based on named dimensions. Each dimension is supposed to have a unique name. If you pref...

PDL::FFTW - PDL interface to the obsolete FFTW API v2.x

++

++

This module no longer exists on CPAN and is completely unsupported because the underlying fftw-2.x library is obsolete. Please use PDL::FFTW3 instead. The previous releases of PDL::FFTW are all available on BackPAN at <http://backpan.perl.org/authors...

PDL::Func - interpolation, integration, & gradient estimation (differentiation) of functions

This module aims to contain useful functions. Honest....

PDL::Char - PDL subclass which allows reading and writing of fixed-length character strings as byte PDLs

42 ++

42 ++

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...

PDL::Lite - minimum PDL module OO loader

42 ++

42 ++

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", "ndarray", "barf" and "null"). This is the absolute minimum set for PDL. Access to other functi...

PDL::Math - extended mathematical operations and special functions

42 ++

42 ++

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...
