PDL::Modules


NAME

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


DESCRIPTION

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


LOOKING FOR A FUNCTION?

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

 pdl> 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 PDL shell, see perldl or pdl2.
