Evaluating a function on multiple points

Question

Is it possible to evaluate a function on a numpy array of points, or do I just need to loop through and compute the value at each point?

Maybe this helps you:

It is basically the same question. But it seems that without extra tools a for-loop is necessary to evaluate a function.

Not exactly. I was hoping for some kind of vectorized operation, without any explicit for looping. Right now I'm doing, in 1D:

xx = np.linspace(0, 1, num=100)
uu = np.zeros_like(xx)

for i in np.arange(0, xx.size):
    uu[i] = u(xx[i])
