NAME

6       PDL - the Perl Data Language
7

DESCRIPTION

9       (For the exported PDL constructor, pdl(), see PDL::Core or pdl[2])
10
11       PDL is the Perl Data Language, a perl extension that is designed for
12       scientific and bulk numeric data processing and display.  It extends
13       perl's syntax and includes fully vectorized, multidimensional array
14       handling, plus several paths for device-independent graphics output.
15
16       For basic information on the PDL language, see the pdl(1) (lowercase)
17       man page.
18
19       You can run PDL programs directly as perl scripts that include the PDL
20       module (with "use PDL;"), or via an interactive shell (see the
21       perldl(1) man page).
22
23       The PDL language extension includes about a dozen perl modules that
24       form the core of the language, plus additional modules that add further
25       functionality.  The perl module "PDL" loads all of the core modules
26       automatically, making their functions available in the current perl
27       namespace.  See also PDL::Lite or PDL::LiteF if start-up time becomes
28       an issue.
29
30       EXPORTS:
31          "use PDL;" exports a large number of routines into the calling
32          namespace.  If you want to avoid namespace pollution, you must
33          instead "use PDL::Lite", and include any additional modules explic‐
34          itly.
35
36       NICESLICE:
37          Note that the PDL::NiceSlice syntax is NOT automatically loaded by
38          "use PDL;".  If you want to use the extended slicing syntax in a
39          standalone script, you must also say "use PDL::NiceSlice;".
40
41       PDL::Math:
42          The PDL::Math module has been added to the list of modules for ver‐
43          sions later than 2.3.1. Note that PDL::Math is still not included in
44          the Lite and LiteF start-up modules.
