PDL -- the package
------------------
The Perl Data Language (a.k.a. PerlDL or PDL) project aims to turn perl
into an efficient numerical language for scientific computing. The PDL
module gives standard perl the ability to COMPACTLY store and SPEEDILY
manipulate the large N-dimensional data sets which are the bread and
butter of scientific computing. e.g. $a=$b+$c can add two 2048x2048
images in only a fraction of a second.
The aim is to provide tons of useful functionality for scientific and
numeric analysis.
Check the pdl web site at http://pdl.perl.org for more information.
Installation
------------
Please read the file INSTALL for information on how to
configure and install PDL. The Release_Notes and Known_problems
files contain important version specific information. Be *sure*
to read Known_problems if you have any INSTALL issues.
Once you have built PDL and either installed it or done
'make doctest', try either
perl -Mblib Perldl2/pdl2
from within the root of the PDL tree or just
pdl2
if you have installed PDL already ('make install') to get the
interactive PDL shell. In this shell, 'help' gives you
access to PDL documentation for each function separately
('help help' for more about this) and 'demo' gives you some
basic examples of what you can do.
Bug Reports
-----------
You can check the existing PDL bugs on GitHub at
https://github.com/PDLPorters/pdl/issues
The mailing list archives can be searched/read at
http://pdl.perl.org/?page=mailing-lists
Questions about problems and possible bugs can be discussed
via the pdl-general mailing list. This is very useful if you are
not sure what you have is a bug or not. For example, the list
is the place to go for install problems.
If you need to post a problem report, and after checking with
the pdl-general list that it *is* a bug, please use the GitHub issue
tracker system following the guidance in the BUGS file.
