MATLAB Functions Help Desk

lookfor

Purpose

Keyword search through all help entries

Syntax

Description

lookfor topic searches for the string topic in the first comment line (the H1 line) of the help text in all M-files found on MATLAB's search path. For all files in which a match occurs, lookfor displays the H1 line.

lookfor topic -all searches the entire first comment block of an M-file looking for topic.

Examples

For example

finds at least a dozen matches, including H1 lines containing "inverse hyperbolic cosine," "two-dimensional inverse FFT," and "pseudoinverse." Contrast this with

or

These commands run more quickly, but probably fail to find anything because MATLAB does not ordinarily have a function inverse.

In summary, what lists the functions in a given directory, which finds the directory containing a given function or file, and lookfor finds all functions in all directories that might have something to do with a given keyword.
