Other MathWorks country sites are not optimized for visits from your location. Doing both of those by way of extra input and output arguments of the main function does not seem like good programming practice, and at that point it would make more sense to have an independent function like you were talking about initially. MATLAB functions must be defined in separate files and function name must match with the file name. Making statements based on opinion; back them up with references or personal experience. .
