Hello, Shaul Salomon. Besides the existing checking for 'forbidden' commands in your Test Suite, which can report false positives (e.g. discussion of "cosine" in comments), you could consider a more complicated regexp statement, or perhaps use the assessFunctionAbsence function described at https://au.mathworks.com/help/coursework/ug/assessfunctionabsence.html . —DIV
