How do I list all my dependent m-Files?

I want to generate a list of all the dependent m-files for a particular MATLAB script file that I wrote (just my own functions, not built-in functions). I used to know how to do this, but it has been a few years.

Try this:

% List required files and toolboxes.  Displays them in the command window or console window (if deployed).
% Sample call
% 		fullFileName = [mfilename('fullpath'), '.m'];
%       DisplayRequiredFunctions(fullFileName)
% It takes a long time to run so that's why I only do it in the development environment.
function DisplayRequiredFunctions(fullFileName)
try
	if ~isdeployed
		[~, baseFileNameNoExt, ext] = fileparts(fullFileName);
		baseFileName = [baseFileNameNoExt, '.m'];
		[requiredFileList, toolboxList] = matlab.codetools.requiredFilesAndProducts(fullFileName);
		fprintf('Required m-files for %s:\n', baseFileName);
		for k = 1 : length(requiredFileList)
			fprintf('    %s\n', requiredFileList{k});
		end
		fprintf('Required MATLAB Toolboxes for %s:\n', baseFileName);
		for k = 1 : length(toolboxList)
			fprintf('    %s\n', toolboxList(k).Name);
		end
	end
catch ME
end

Dear Image Analyst,

Thank you kindly.

The issue is I have a friend with an old shipwrecked copy of ML, and he doesn't have access to R>2016, and cannot access matlab.codetools.*

I tried the 'depfun' answers but that ran super-slow and I had to abort...

Was looking for an (antiquated) answer that didn't use the new stuff.

If I can't find it, then so be it..

He can give you his code and you can do it.

Dear Image Analyst,

I used matlab.codetools.requiredFilesAndProducts for a similar problem. But I found that it only lists the dependencies that I actually have. It does not seem to list the dependencies that are missing.

I inherited a very complex script that calls long chains of functions and I am trying to figure out which ones are missing.

Thanks for any more advice

Try the "Tools->Save and Show Dependency Report" from the MATLAB pulldown menus, or else try these File Exchange submissions:

depfunToolbox: http://www.mathworks.com/matlabcentral/fileexchange/14176-depfuntoolbox

fdep: http://www.mathworks.com/matlabcentral/fileexchange/17291

To me, fdep looks like the most comprehensive.

[Scott Sather]

The Dependency Report is closer to what I want, but it missed a lot of functions that are called, plus it includes a lot of my GUI CreateFcn and Callback functions which are all in the same file. I remember running something within the Command Window and it returned a brief list of the dependent m-files.

[Image Analyst]

That's true. That's when I discovered fdep. It finds EVERYTHING, including stuff Dependency Report might miss. Make a shortcut on your toolbar and paste this code, then be sure to change the folder in my code from "C:\Program Files\MATLAB\work\UserExamples\fdep" to where YOU have fdep saved.

% Examine an m-file for what toolboxes or other m-files it calls.
addpath(genpath('C:\Program Files\MATLAB\work\UserExamples\fdep'));
% Let the user browse for the m-file. 
[baseFileName, folder] = uigetfile('*.*', 'Specify an m-file'); 
% fprintf(1, 'baseFileName = %s\n', baseFileName);
% Create the full filename.
fullFileName = fullfile(folder, baseFileName);
if exist(fullFileName, 'file')
 fprintf(1, 'Running fdep on %s\n', fullFileName);
 %cd('C:\Program Files\MATLAB\work\UserExamples\fdep');
 % Get its dependencies by passing it to the fdep function.
 p=fdep(fullFileName);
 p.list();
else
 fprintf(1, 'User clicked Cancel. fdep() was not run.\n');
 return;
end

[Scott Sather]

Thanks, this worked for me, but not at first. Then I realized that the functions it wasn't picking up were located in another folder that only gets added to the path within the main script file. After adding that path manually and rerunning your script, the entire set of dependencies appears.

Thanks again.

[Sean Lynch]

depfun has been replaced with matlab.codetools.requiredFilesAndProducts

Answer 4

[Kaustubha Govind]

You can use depfun.

[Scott Sather]

I already tried depfun - it took forever and I eventually had to cancel it. There is a simple method to do this that produces near instant results.

[Josh Philipson]

Scott, so what is the simple method?

[Sean de Wolski]

Perhaps:

doc depfun

?

[Scott Sather]

Have you ever used this yourself?

[Sean de Wolski]

It does expect its input to be a function.
