checking a matlab function for nested functions

7 views (last 30 days)
how to find programatically if a matlab function m file contains nested function.
fileData = mlintmex('-calls',which(fileName));
fileData = regexp(fileData,'[NS](\d+) (\d+) \d+ (\w+)\n','tokens');
gives the list of function within fileName. My question is how to distinguish local functions from nested functions?
Best regards

I have found the answer to my question. The undocumented function mtree contains all the necessary infos. The only difficulty is to find where to search. The wrapper getcallinfo, another undocumented function gives a good approach to retrieve what I am asking for, once all the nested struct fields have been visited.

You could easily find all function definitions by opening the m-file as a text file, using fgetl() to get a line, then using contains() or startsWith() to see if the line contains a function definition
fid = fopen(mFileName, 'rt');
textLine = fgetl(fid);
while ischar(textLine)
if startsWith(strtrim(textLine), 'function ')
% It's a function definition...
end
textLine = fgetl(fid); % Read next line
end
fclose(fid);

See the attached function to list all the dependent m-files.

I use directly matlab.codetools.requiredFilesAndProducts(). However the local functions don't appear, only the main function whose name is attached to file name.
