|MATLAB Function Reference|
Search for specified keyword in all help entries
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
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
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.
Even more extensive than the
lookfor function is the find feature in the Current Directory browser. It looks for all occurrences of a specified word in all the M-files in the current directory. For instructions, see Finding and Replacing Content Within Files.
