PDL::Ops - Fundamental mathematical operators

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::Lvalue - declare PDL lvalue subs

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::SV - PDL subclass for keeping scalar data (like strings)

This PDL::SV class stores array of scalar values. It can be used for vectors of strings. While this class is a subclass of PDL, its internals are quite different from other normal PDL types. So basically what's not documented are not guarenteed to wo...

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

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 character grids. The indexing is done on a string level and n...
