NAME

PDLA::Modules - A guide to PDLA's module reference.

DESCRIPTION

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

LOOKING FOR A FUNCTION?

If you want to search for a function name, you should use the PDLA shell along with the "help" or "apropos" command (to do a fuzzy search). For example:

 pdla> apropos xval
 xlinvals        X axis values between endpoints (see xvals).
 xlogvals        X axis values logarithmicly spaced...
 xvals           Fills a piddle with X index values...
 yvals           Fills a piddle with Y index values. See the CAVEAT for xvals.
 zvals           Fills a piddle with Z index values. See the CAVEAT for xvals.

To learn more about the PDLA shell, see perldla or pdla2.
