PDL::Objects — Object-Orientation, what is it and how to exploit it DescriptionThis still needs to be written properly. [Also, is there a good reason we don’t recommend storing extra object data in the header hash?] InheritanceThere are basically two reasons for subclassing piddles. The first is simply that you want to be able to use…
PDL::Modules – A guide to PDL’s module reference. DescriptionThis 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 comprehensive…
PDL::MATLAB – A guide for MATLAB users. IntroductionIf 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, as…
PDL::Internals – description of some aspects of the current internals DescriptionIntroThis 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 functions, you…
PDL::Indexing – Introduction to indexing and slicing piddles. OverviewThis 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 parallel…
PDL::FAQ – Frequently asked questions about PDL VersionCurrent FAQ version: 1.004 DescriptionThis is version 1.004 of the PDL FAQ, a collection of frequently asked questions about PDL – the Perl Data Language. About This DocumentQ: 1.1 Where to find this documentYou can find the latest version of this document at <http://pdl.perl.org/?docs=FAQ&title=Frequently%20Asked%20Questions> . Q: 1.2 How…
PDL::Delta – PDL changes between V1.0 and V2.0 DescriptionThis file is an attempt to list the major user-visible changes between PDL versions 1.0 and 2.0. Core ChangesPiddles 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) because of speed…
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]WarningDataflow is very experimental. Many features of it are disabled for 2.0, particularly families for one-directional dataflow. If you wish to use one-directional dataflow…
PDL::Course – A journey through PDL’s documentation, from beginner to advanced. Author, DateThis is written by David Mertens with edits by Daniel Carrera. PrefacePDL‘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 document is…
PDL::Bugs – How to diagnose and report PDL problems Versionversion 1.0000 DescriptionThis 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 ProblemThe primary…
PDL::BadValues – Discussion of bad value support in PDL DescriptionWhat 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 due to…
PDL::API – making piddles from Perl and C/XS code DescriptionA 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 C/XS…
PCPIntro – introduction to the Performance Co-Pilot (PCP) IntroductionThe Performance Co-Pilot (PCP) is a toolkit designed for monitoring and managing system-level performance. These services are distributed and scalable to accommodate the most complex system configurations and performance problems. PCP supports many different platforms, including (but not limited to) Linux, MacOSX, Solaris and Windows. From a…
Markdown.pl – Convert Markdown syntax to (X)HTML DescriptionThis 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 *…
