(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...

An implementation of online docs for PDL....

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....

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

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...

This module features a growing number of functions manipulating complex numbers. These are usually represented as a pair "[ real imag ]" or "[ magnitude phase ]". If not explicitly mentioned, the functions can work inplace (not yet implemented!!!) an...

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

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...

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

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...

This module no longer exists on CPAN and is completely unsupported because the underlying fftw-2.x library is obsolete.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...

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...

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...

With Test::PDL, you can compare two piddles for equality. The comparison is performed as thoroughly as possible, comparing types, dimensions, bad value patterns, and finally the values themselves. The exact behaviour can be configured by setting cert...
