Slicing is a basic, extremely common operation, and PDL's slice method would be cumbersome to use in many cases. "PDL::NiceSlice" rectifies that by incorporating new slicing syntax directly into the language via a perl *source filter* (see the perlfi...

This plugin enables one to use the PDL::NiceSlice syntax in an instance of "Devel::REPL" such as the new Perldl2 shell, "pdl2". Without the plugin, array slicing looks like this: pdl> use PDL; pdl> $x = sequence(10); $PDL1 = [0 1 2 3 4 5 6 7 8 9]; pd...

(For the exported PDL constructor, pdl(), see PDL::Core) PDL is the Perl Data Language, a perl extension that is designed for scientific and bulk numeric data processing and display. It extends perl's syntax and includes fully vectorized, multidimens...

Methods and functions for type conversions, PDL creation, type conversion, threading etc....

Loads modules named below, making the functions available in the current namespace. Properly formated documentations online at http://pdl-stats.sf.net...

This package provides many of the powerful PerlDL core index manipulation routines. These routines mostly allow two-way data flow, so you can modify your data in the most convenient representation. For example, you can make a 1000x1000 unit matrix wi...

This module provides some primitive and useful functions defined using PDL::PP and able to use the new indexing tricks. See PDL::Indexing for how to use indices creatively. For explanation of the signature format, see PDL::PP....

The terms FUNCTIONS and METHODS are arbitrarily used to refer to methods that are threadable and methods that are NOT threadable, respectively. Plots require PDL::Graphics::PGPLOT. ***EXPERIMENTAL!*** In particular, bad value support is spotty and ma...

Provides methods to read and write Nifti files, read, write and manipulate the header based on PDL. my $nii=PDL::IO::Nifti->new($pdl); $nii->write_nii($file); is all you need to do to save your data....

This module provides a number of PDL-threaded functions and bindings for use with the Prima toolkit. Many of the functions are PDL bindings for the standard Prima drawing functions. Others are useful functions for color manipulation, or getting data ...

The terms FUNCTIONS and METHODS are arbitrarily used to refer to methods that are threadable and methods that are NOT threadable, respectively. FUNCTIONS except ols_t support bad value. PDL::Slatec strongly recommended for most METHODS, and it is req...

This module allows to solve N-th order M dimensional ordinary differential equations. It uses the adaptive stepsize control for fifth order Cash-Karp Runge-Kutta algorithm described in "Numerical Recipes in Fortran 77: The Art of Scientific Computing...

Levenberg-Marquardt routines for least-squares fit to functions non-linear in fit parameters. This module provides a PDL ( PDL::PDL ) interface to the non-linear fitting library levmar 2.5 (written in C). Levmar is thread aware (in the PDL sense), pr...

The terms FUNCTIONS and METHODS are arbitrarily used to refer to methods that are threadable and methods that are NOT threadable, respectively. Does not have mean or median function here. see SEE ALSO....

Assumes that we have data pdl dim [observation, variable] and the goal is to put observations into clusters based on their values on the variables. The terms "observation" and "variable" are quite arbitrary but serve as a reminder for "that which is ...

This module provides a means to share PDL data between different Perl threads. In contrast to PDL's posix thread support (see PDL::Parallel::CPU or, for older versions of PDL, PDL::ParallelCPU), this module lets you work with Perl's built-in threadin...

One of Perl's mottos is to "make easy things easy, and hard things possible." The bulk of the modules provided by the PDL::Graphics::Prima distribution focus on the latter half, making hard but very powerful things possible. This module tackles the o...

In my experience, parallel algorithms are nearly always expressed in a form called single-instruction, multiple-dataset (SIMD). That is, the exact same code runs in multiple threads, and the only difference between the threads is the data they manipu...

This profile is for development of the new PDL shell (version 2). The preferred method to start the new shell is via the "pdl2" command. This documentation is provided for "Devel::REPL" coders that may wish to use this profile directly for their deve...
