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

73 views (last 30 days)
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;
run(fullfile(folder, file));
success(k) = true;
fprintf('failed: %s\n', file);

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
file = getListOfFiles;
function testFileDoesNotError(testCase, file)
run(fullfile('C:\YourFolder', file));
function files = getListOfFiles
list = dir(fullfile('C:\YourFolder', '*.m'));
files = {};
Then you can run them all and get your results:
result = runtests('TestAllFiles')
logicalVector = [result.Passed];
