is there a code to open and run all m files in a folder?

Hi, I have multiple (about 50) different .m files in a folder. I wish to open and run each and every one of them using a matlab script. the output of this script would be a logical vector indicating which files had errors and which did not.

so is there a matlab code/ function that can open, run and check if there were run errors? thanks

What about this:

folder  = 'C:\YourFolder';
list    = dir(fullfile(folder, '*.m');
nFile   = length(list);
success = false(1, nFile);
for k = 1:nFile
  file = list(k).name;
  try
    run(fullfile(folder, file));
    success(k) = true;
  catch
    fprintf('failed: %s\n', file);
  end
end

Hi, Great! that did it! a few notes though. this script should not be inside the folder being checked ( got myself to an infinite loop there).

and another question, is there a way to go over the file to see if a certain string appears ? say i want to check all of the file that managed to run if they have the "figure" code.

You can check if the mfile is the current file using MFILENAME, as in,

if ~strcmpi(fullfile(folder, file), mfilename('fullpath'))
...

I don't know what "the figure code" is. Do you mean if the m-file has an associated .fig file? Or do you mean if the word "figure" appears inside the m-file, especially as a statement/function call? Anyway, to see if a certain string appears in another string, you can use strfind().

I don't know if there is a built-in function, but I think you could fairly easy make one yourself. Using the command dir you can acquire all the file names in a folder, then just loop through them, running them one-by-one.

To expand on per's answer, in R2014a you can do this using parameterized tests:

classdef TestAllFiles < matlab.unittest.TestCase

      properties(TestParameter)
          file = getListOfFiles;
      end

      methods(Test)
          function testFileDoesNotError(testCase, file)
              run(fullfile('C:\YourFolder', file));
          end
      end
  end

function files = getListOfFiles
list    = dir(fullfile('C:\YourFolder', '*.m'));
files = {list.name};
end

Then you can run them all and get your results:

result = runtests('TestAllFiles')
logicalVector = [result.Passed];

thank you. i already implemented what Jan offered but ill look into this as well.

Yes, there is

• Unit Testing Framework, Write and run tests for MATLAB programs

This is much more than than you are asking for, however, it well worth to start applying Unit Testing. See http://software-carpentry.org/v4/test/ and http://stackoverflow.com/questions/67299/is-unit-testing-worth-the-effort

And see:

• Code Analyzer Report
• checkcode, Check MATLAB code files for possible problems
