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.
