NAME

6       PDL::Modules - A guide to PDL's module reference.
7

DESCRIPTION

9       This page serves as a table of contents for PDL's module documentation.
10       This page does not list every single PDL module. It only shows the ones
11       intended for PDL users, while omitting those which are deemed "for
12       internal use only". If you wish to see a comprehensive list of all
13       documentation, please see the PDL::Index page.
14

LOOKING FOR A FUNCTION?

16       If you want to search for a function name, you should use the PDL shell
17       along with the "help" or "apropos" command (to do a fuzzy search).  For
18       example:
19
20        pdl> apropos xval
21        xlinvals        X axis values between endpoints (see xvals).
22        xlogvals        X axis values logarithmicly spaced...
23        xvals           Fills a piddle with X index values...
24        yvals           Fills a piddle with Y index values. See the CAVEAT for xvals.
25        zvals           Fills a piddle with Z index values. See the CAVEAT for xvals.
26
27       To learn more about the PDL shell, see perldl or pdl2.
