Matlab: how to find functions on path that use a given function

Question

It sometimes happens that I need to change the behavior of a function. Is there an easy way to find functions (on the matlab path) that use that function?

Answer 1

Start with help deprpt.

EDIT: when I run a dependency report there are 3 checkboxes at the top of the report window. One of these, by default unchecked, is called 'Show parent functions (current folder only)'. That is probably the beginning of what you want but it only works in a single folder.

If you want more than that, I suggest that you try edit deprpt.m.

Answer 2

The way I do this is to look for files that contain the name of the function I'm interested in. Thus, I don't only see who calls my function, but also what signature they use.

In the editor: Edit->Find Files

Answer 3

you mean like looking for dependencies? that would be tools -> show dependency report

Answer 4

I would use a tool like grep. I posted a tool called mgrep on the file exchange a few years ago. It can search through entire directories of m-files for any given string, and it searched recursively down into sub-directories. So to find functions in my directories that call fminsearch, I would merely execute this at the command line.

mgrep('fminsearch','.','show','off') Searching directory(ies)...
