How to find out all the functions/mfiles that calls a specific function/mfile?

I create some functions and mfiles. And I want to change the name of a function, say 'wantchang'. However, 'wantchang' is called by some others(function or mfile). How to find all the mfile that calls 'wantchang'?

Hy,

when I had this sort of problem with a punch of mfiles and functions I used notepad++ - here you can add the folder of your files into a search and it will show you all files where "wantchang" is implied!

Thank you, Robert.

Hello,

Is there a way to do this in MATLAB?

Thank you in advance.

Best,

Use 'Find Files' from the editor and make sure it includes everything on your path. If your search phrase is common and used in other contexts it can be a problem, but usually a mixture of matching case and whole word narrows it down.

You can use one of the dependency reporters from the file exchange:

http://www.mathworks.com/matlabcentral/fileexchange/?utf8=%E2%9C%93&term=dependency

But searching for "wantchang(" would be easier: Click on "Find Files" in the editor, "Find Files containing text", "Look in entire Matlab path" and select "Include subfolders" on demand to consider @Object and /private folders.

If you have to change less than 100 occurrences, I'd prefer to aplly the changes manually, because the automatic replacement is dangerous.

Searching for "wantchang(" fails, if you have code like:

wantchang (Args)
wantchang NonfunctionalForm
wantchang ...
  (Arguments, in, the, next, line)
feval('wantchang', Args)
eval(lower('WANTCHANG(ARGS)'))
fcn = @wantchang;
fcn(Args)

Pcoded files are not considered also. In such cases the dependency reporters are smarter.
