NAME

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

DESCRIPTION

This page serves as a table of contents for 's module documentation. This page does not list every single module. It only shows the ones intended for 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 PDL::Index page.

LOOKING FOR A FUNCTION?

If you want to search for a function name, you should use the 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

shell, see perldl or pdl2.
