function z = mysub(x,y)
z = num2str( str2num(x) - str2num(y) );
why this is not working for this code?
Hi. My code only prints out '-' for a negative number but not '+' for a positive. Can anyone help? function Z = mysub(X,Y); W = (str2num(X))-(str2num(Y)); Z = num2str(W); end
actually each of them has 14 characters or less...15 if we count the signs.
Mark Sanderson, if W > 0 Z = ['+' ...]
