PDL (``Perl Data Language'') gives standard perl the ability to
|
|
COMPACTLY store and SPEEDILY manipulate the large N-dimensional data
|
|
arrays which are the bread and butter of scientific computing.
|
|
|
|
The idea is to turn perl in to a free, array-oriented, numerical
|
|
language in the same sense as commerical packages like IDL and
|
|
MatLab. One can write simple perl expressions to manipulate entire
|
|
numerical arrays all at once. For example, using PDL the perl variable
|
|
$a can hold a 1024x1024 floating point image, it only takes 4Mb of
|
|
memory to store it and expressions like $a=sqrt($a)+2 would manipulate
|
|
the whole image in a few seconds.
|
|
|
|
A simple interactive shell (perldl) is provided for command line use
|
|
together with a module (PDL) for use in perl scripts.
