NAME

       PDL::Tutorials - A guide to PDL's tutorial documentation.

MIGRATION

       These are our migration guides for users familiar with other types of numerical analysis
       software.

       PDL::MATLAB
            Migration guide for MATLAB users. This page explains the key differences between
            MATLAB and PDL from the point of view of a MATLAB user.

       PDL::Scilab
            Migration guide for Scilab users. This page explains the key differences between
            Scilab and PDL from the point of view of a Scilab user.

FOUNDATION

       PDL::Philosophy
            Why did we write PDL? This document explains some of the history and motivation
            behind the Perl Data Language. It is an attempt to answer the question "Why PDL?".

       PDL::QuickStart
            Quick introduction to PDL features. A hands-on guide suitable for complete beginners.
            This page assumes no previous knowledge of Perl or PDL.

       PDL::Indexing
            After you have read the QuickStart guide, you should follow up with this document.
            This guide goes more deeply into the concepts of "indexing" and "slicing" and how
            they form the core of numerical analysis with PDL.

INTERMEDIATE

       PDL::Threading
            Threading is one of PDL's most powerful features. If you know MATLAB, you've heard of
            "vectorizing". Well, threading is like "vectorizing on steroids". It lets you make
            very fast and compact code by avoiding nested loops. All vector-based languages do
            this, but PDL generalizes the technique to all sorts of applications.

            This tutorial introduces PDL's threading feature, and it shows an example
            implementing Conway's Game of Life in 10 lines and 80 times faster than a classical
            implementation.

       PDL::BadValues
            Sometimes it is useful to specify that a certain value is "bad" or "missing".
            Scientific instruments some times include portions of invalid data. For example, a
            CCD camera might produce an image with over-exposed pixels. PDL's "bad values"
            feature gives you an easy way to deal with this sort of imperfect data.

       PDL::Tips
            Tips and suggestions for using PDL. This page is an assorted collection of
            programming tidbits that some PDL users have found useful. Some of these tips might
            be of help when you write your programs.

ADVANCED

       PDL::PP
            PDL's Pre-Processor is one of PDL's most powerful features. You write a function
            definition in special markup and the preprocessor generates real C code which can be
            compiled. With PDL:PP you get the full speed of native C code without having to deal
            with the full complexity of the C language.

       PDL::API
            A simple cookbook explaining how to create piddle manually, either from Perl or from
            C/XS code. This page covers the PDL core routines that comprise the PDL API. If you
            need to access piddles from C/XS, this is the document for you.

       PDL::Internals
            Description of the inner workings of the PDL module. Very few people need to see
            this. This page is mainly for PDL developers, or people interested in debugging PDL
            or changing the internals of PDL. If you can read this document and understand all of
            it, and you additionally understand PDL::PP, you will be awarded the title of "PDL
            Guru".
