There is no single MATLAB command that will give you all the MATLAB related files in a directory and its subdirectories, but it is possible to process the
output of the GENPATH command to produce the desired result.
The MATLAB command GENPATH returns a string consisting of a folder and all its subfolders separated by the PATHSEP:
mkdir a
mkdir a\b
p = genpath('a')
produces the output:
p =
a;a\b;
Running REGEXP on p with the 'split' option produces a cell array of
the individual subdirectories:
s = regexp(p, pathsep, 'split')
which produces the output:
s =
'a' 'a\b' ''
(Note that there is an empty string at the end because of that final trailing semicolon in p)
We can now loop through the cell array s and run the WHAT command on each folder:
for k=1:length(s)-1 % subtract one to skip over that last empty string
what(s{k})
end
The file recursive_what.m combines the above steps into a MATLAB function.
Caveats: the 'split' option to REGEXP is new in 2007b.
You can get more information about GENPATH, PATHSEP and REGEXP from inside MATLAB by typing
