PDL::Modules1p
A guide to pdl's module reference.
Overview
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 xvalxlinvals X axis values between endpoints (see xvals).xlogvals X axis values logarithmicly spaced...xvals Fills an ndarray with X index values...yvals Fills an ndarray with Y index values. See the CAVEAT for xvals.zvals Fills an ndarray with Z index values. See the CAVEAT for xvals.
To learn more about the PDL shell, see perldl or pdl2.
