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

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.
