% Filename: ex.m % function ex=ex(x,y) % ex=x.*x+y.*y; % end syms x y; u=jacobian(ex(x,y),[x,y])

With your spacing it is difficult to tell what is commented out and what is not commented out.

If it is still a function, then notice that it does not assign to ex as the function expects.

It is not recommended, by the way, to use the same name for a variable as the function; it confuses the parser and it confuses readers.
