Totally out of curiosity, could you be a bit more concrete in your posted example? I can't get it to work (I'm inexperienced with numpy and I'm messing something when translating your quick example to python)

Thanks!

Yea sorry that was just pseudo code. You want it in this form:

    centers = np.array([
        [3, 3],
        [4, 4]
    ])
    point = np.array([3.5, 3.5])
    vals = centers - point
    np.linalg.norm(vals, axis=1)
