MATLAB: Problem with running m file

running file

When I run a very simple m (prob.m ) file as: x = 1; y = 2; z= x+y;

I get the right answer in the workspace, but the command window just says the name of the file. What am I doing wrong?

Sounds like you want to toggle output on and off probably for debugging purpose. In that case, you should be using the debugging tools instead.

Otherwise, a well written program should be explicit about wanting to display something to the command window, not leave it to the absence of a semi-colon, which most people (and matlab code analyser) would consider a coding error. So:

something = someexpression;   %always terminate with semicolon
if dooutput
    disp(something);      %Now it's clear that you want to display it and that it's not a mistake
end

There is no direct, built-in way to globally control the placement of semi-colons in MATLAB files. You will have to write custom scripts to do that.

See attached function called fixSemiColon() which calls readLineOfFile() and replaceFileLine() and shows a way of doing this.
