List all files with extension 'ext' in the current directory.
Return a char matrix with the name of files in rows.
Return 0 if no files.
The problem can't run because the Test Suite issues mkdir; cd test.
The call to filerep.m is no longer on the path. Suggest eliminate mkdir and cd lines.
The mkdir test; and cd test issue makes it impossible to make any submissions.
Sorry. It's OK now.
My answer 15 is Donkey. Did just to show test Suite could be gamed. Also did not know how to get dir *.ext, which was frustrating me as I left out the ()s. Suggest add a fn=['saveme.mat' num2str(randi(9,1,1))] and then do your save fn with ext=fn(8:11). Then rescore solution 15. This will cut out the cheats. Good problem update of addpath. The Test Suites are more complex than the solutions sometimes.
