lookfor - Search for keyword in all help entries

GUI Alternatives

As an alternative to the lookfor function, use the Function Browser.

Syntax

lookfor topic lookfor topic -all

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 the MATLAB 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:

lookfor inverse

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

which inverse

what inverse

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

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

Even more extensive than the lookfor function are the find features in the Current Folder browser. For example, you can look for all occurrences of a specified word in all the M-files in the current folder. For more information, see Finding Files and Folders
