MODULES(1)

📦 version 2.78.0, in epel 9

💖 NAME 💖

PDL::Modules — a guide to PDL's module reference. This is the MODULES(1) page from the user-contributed Perl documentation, and it's basically your map to the PDL module docs. 🗺️✨

💖 DESCRIPTION 💖

Okay so this page is a table of contents for PDL's module documentation. Important: it 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, use the PDL shell along with the help or apropos command — apropos gives you a fuzzy search. 🕵️‍♀️ For example:

pdl> apropos xval
xlinvals        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.
