Getting Started with PDL

Early this month, I wrote an introduction to the Perl Data Language (PDL). Here is the Introduction:

Imagine you, Just Another Perl Hacker, were assigned to this new project that involves heavy numerical computation. Most of your peers recommend you to use C or C++. Some others recommend you the language of the Snake -sorry I forgot the name ;-). What can you do if you really want to keep using Perl? Using PDL is the answer. The Perl Data Language (PDL) is a package that gives Perl the ability to compactly store and speedily manipulate the large N-dimensional data sets that are common in scientific and other data intensive programming tasks. To achieve such a great performance, PDL uses C (and sometimes Fortran) to efficiently handle multidimensional data sets. For the rest of the tutorial, I will assume you have a working copy of PDL already installed. Once you have PDL installed, you can use it in Perl scripts by simply declaring: use PDL;. If you have not yet installed PDL, I will recommend you to have a look at the Appendix for some of the pre-requisites for having PDL installed without problems. And if you get into troubles, I recommend you to ask in one of the PDL mailing lists or here at the Monastery. Now, we are ready to start.

 

The full tutorial is available at PerlMonks.

 

Cheers,

Lino.
