Note, that if the lines below are in add.m, then add(x,y) calls that function.

        function total=addr(x,y)
                total=x+y;
        endfunction

If the same lines are typed at the command prompt then add(x,y) is calling 
something else ... likely a function saved in a file with the name add.m.

You can check by typing ...

        which add
