PDL::Objects — Object-Orientation, what is it and how to exploit it Description This still needs to be written properly. [Also, is there a good reason we don’t recommend storing extra object data in the header hash?] Inheritance There are basically two reasons for subclassing piddles. The first is simply that you want to be able…
PDL::Modules – A guide to PDL’s module reference. Description This page serves as a table of contents for PDL‘s module documentation. This page does not list every single PDL module. It only shows the ones intended for PDL users, while ommitting those which are deemed “for internal use only”. If you wish to see a…
PDL::MATLAB – A guide for MATLAB users. Introduction If you are a MATLAB user, this page is for you. It explains the key differences between MATLAB and PDL to help you get going as quickly as possible. This document is not a tutorial. For that, go to PDL::QuickStart. This document complements the Quick Start guide,…
PDL::Internals – description of some aspects of the current internals Description Intro This document explains various aspects of the current implementation of PDL. If you just want to use PDL for something, you definitely do not need to read this. Even if you want to interface your C routines to PDL or create new PDL::PP…
PDL::Indexing – Introduction to indexing and slicing piddles. Overview This man page should serve as a first tutorial on the indexing and threading features of PDL. Like all vectorized languages, PDL automates looping over arrays using a variant of mathematical vector notation. The automatic looping is called “threading”, in part because ultimately PDL will implement…
PDL::FAQ – Frequently asked questions about PDL Version Current FAQ version: 1.004 Description This is version 1.004 of the PDL FAQ, a collection of frequently asked questions about PDL – the Perl Data Language. About This Document Q: 1.1 Where to find this document You can find the latest version of this document at <http://pdl.perl.org/?docs=FAQ&title=Frequently%20Asked%20Questions>…
PDL::Delta – PDL changes between V1.0 and V2.0 Description This file is an attempt to list the major user-visible changes between PDL versions 1.0 and 2.0. Core Changes Piddles are not hashes any more: $a = zeroes 10,10; $$a{FOO} = "bar" doesn’t work. They are currently scalar references (to opaque C structures in finer terms)…
PDL::Dataflow — description of the dataflow philosophy Synopsis pdl> $a = zeroes(10); pdl> $b = $a->slice("2:4:2"); pdl> $b ++; pdl> print $a; [0 0 1 0 1 0 0 0 0 0] Warning Dataflow is very experimental. Many features of it are disabled for 2.0, particularly families for one-directional dataflow. If you wish to use…
PDL::Course – A journey through PDL’s documentation, from beginner to advanced. Author, Date This is written by David Mertens with edits by Daniel Carrera. Preface PDL‘s documentation is extensive. Some sections cover deep core magic while others cover more usual topics like IO and numerical computation. How are these related? Where should you begin? This…
PDL::Bugs – How to diagnose and report PDL problems Version version 1.0000 Description This module explains how to get help with a PDL problem and how, when, and where to submit a bug report. In the future it may be extended to provide some sort of automated bug reporting capability. If You Have A Pdl…
PDL::BadValues – Discussion of bad value support in PDL Description What are bad values and why should I bother with them? Sometimes it’s useful to be able to specify a certain value is ‘bad’ or ‘missing’; for example CCDs used in astronomy produce 2D images which are not perfect since certain areas contain invalid data…
PDL::API – making piddles from Perl and C/XS code Description A simple cookbook how to create piddles manually. It covers both the Perl and the C/XS level. Additionally, it describes the PDL core routines that can be accessed from other modules. These routines basically define the PDL API. If you need to access piddles from…

Markdown.pl – Convert Markdown syntax to (X)HTML Description This program is distributed as part of Perl’s Text::Markdown module, illustrating sample usage. Markdown can be invoked on any file containing Markdown-syntax, and will produce the corresponding (X)HTML on STDOUT: $ cat file.txt This is a *test*. Absolutely _nothing_ to see here. _Just a **test**_! * test…
