(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...

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....

An implementation of online docs for PDL....

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...

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

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...

This module is loaded when you do "use PDL", "Use PDL::Lite" or "PDL::LiteF". Implementation details are given in PDL::BadValues....

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This module no longer exists on CPAN and is completely unsupported because the underlying fftw-2.x library is obsolete.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

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...

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...
