Hello Alan: Thanks, but perhaps my example did not help to explain my real question. Here is a more simple statement of my question. Is there a way to use sympy to differentiate, for example, the function: f = 5*x[0]**2 + 5*x[1]**2 + ...5*x[n]**2, where x is in vector or matrix form to obtain the symbolic answer df/dx = Sum(10*x[i], (i,0,n)) That is, is there some way to write in sympy (Sum(5*x[i]**2, (i, 0,n))).diff()?
