'''Perl Data Language''' (abbreviated '''PDL''') is a set of [[free software]] array programming extensions to the [[Perl|Perl programming language]]. PDL extends the data structures built into Perl, to include large [[Array data structure|multidimensional arrays]], and adds functionality to manipulate those arrays as vector objects. It also provides tools for [[image processing]], [[machine learning]], [[computer model]]ing of physical systems, and graphical plotting and presentation. Simple operations are automatically vectorized across complete arrays, and higher-dimensional operations (such as matrix multiplication) are supported.
