DepSubFun

Locate dependent sub-functions of m-files.

Description

function funnames = DepSubFun(CS,ExcludeRoot);

DEPSUBFUN Locate dependent functions of an M-file.But, unlike DEPFUN, it will look *inside* m-files for *subfunctiosn* and the ability to excludes files that are in the MATLAB root (default).

The intent of finding the subfunctions is to prevent repetition and to identify which functions need to be updated so if you fix one copy, then you will know there are other copies out there that need to be fixed.

The intent of excluding files in the MATLAB root is to find which files must be included in a distribution so they may be uploaded to the MATLAB File Exchange.

INPUTS:
CS, a cellstring of file names (the files you want analysed)

ExcludeRoot, 0 if you want all function names, 1 if you only want the ones not in the MATLAB root.

OUTPUTS
funnames, a cellstring of functions and subfunctions

USAGE
>>d=dir('*.m');
>> DepSubFun({d.name})

I like it; it's also necessary to get GetSubFunNames.m.

[Robert Oostenveld]

The function depends on a subfunction that is not included in the fileexchange release.

If your code uses MATLAB objects, this function returns only the method name, and not the class name, which is unhelpful. Similarly, if you have two sub-functions of the same name in different files, you can't tell which one is being used. Excluding files inside the MATLAB installation is a nice feature, but not for the reasons given: there's no point in identifying sub-functions when looking for dependent *files*. And there are a lot of "fopen" calls without any "fclose" calls, which leaves thousands of open file handles after a few test-runs. And the fact that the function only accepts cell arrays, and not strings, is pretty annoying.
