Any documentation should be included in the app itself, if it is not part of Matlab itself.

"the output of the app is struct with some values"
Here are a couple of ideas.
  1. If the value you're searching for is within a field named data.struct.dsp.refv, search your code for which function produces "refv". If that's too vague (ie, there are many functions where that is found), then you could add "dsp.refv" and so on. Hopefully the functions are modular enough that the output isn't affected by many of the functions.
  2. With structure outputs I often include a "readme" field when producing output. This field contains the function name and a time stamp when the data was produced. Here's an example.
data(i).struct.dsp.readme = sprintf('This output produced in MyFunct() function on %s',datestr(now));
