PDL::Doc::Perldl - commands for accessing PDL doc database from 'perldl' shell
DESCRIPTION
This module provides a simple set of functions to access the PDL documentation of database, for use from the perldl shell and the pdldoc
command-line program.
Currently, multiple matches are not handled very well.
SYNOPSIS
use PDL::Doc::Perldl; # Load all documenation functions
FUNCTIONS
apropos
Regex search PDL documentation database
apropos 'text'
perldl> apropos 'pic'
rpic Read images in many formats with automatic format detection.
rpiccan Test which image formats can be read/written
wmpeg Write an image sequence ((x,y,n) piddle) as an MPEG animation.
wpic Write images in many formats with automatic format selection.
wpiccan Test which image formats can be read/written
To find all the manuals that come with PDL, try
apropos 'manual:'
and to get quick info about PDL modules say
apropos 'module:'
You get more detailed info about a PDL function/module/manual with the "help" function
usage
Prints usage information for a PDL function
Usage: usage 'func'
perldl> usage 'inner'
inner inner prodcuct over one dimension
(Module PDL::Primitive)
Signature: inner(a(n); b(n); [o]c(); )
sig
prints signature of PDL function
sig 'func'
The signature is the normal dimensionality of the functions arguments. Calling with different dimensions causes 'threading' - see "PDL::PP"
for more details.
perldl> sig 'outer'
Signature: outer(a(n); b(m); [o]c(n,m); )
help
print documentation about a PDL function or module or show a PDL manual
In the case of multiple matches, the first command found is printed out, and the remaining commands listed, along with the names of their
modules.
Usage: help 'func'
perldl> help 'PDL::Slices' # show the docs in the PDL::Slices module
perldl> help 'PDL::Intro' # show the PDL::Intro manual
perldl> help 'slice' # show docs on the 'slice' function
badinfo
provides information on the bad-value support of a function
And has a horrible name.
badinfo 'func'
