lookfor topic -all
lookfor topic searches for the string topic in the first comment line (the H1 line) of the help text in all MATLAB® program files found on the search path. For all files in which a match occurs, lookfor displays the H1 line.
finds at least a dozen matches, including H1 lines containing "inverse hyperbolic cosine," "two-dimensional inverse FFT," and "pseudoinverse." Contrast this with
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 MATLAB program files in the current folder and its subfolders. For more information, see Finding Files and Folders.
