MODULES(1)	      User Contributed Perl Documentation	    MODULES(1)

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 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 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.
