Find the index of the maximum value (minimum value) of a multidimensional array

It seems that this can be done. Note

argmax=lambda A:np.unravel_index(np.array(A).argmax(), np.array(A).shape)
argmin=lambda A:np.unravel_index(np.array(A).argmin(), np.array(A).shape)

To use it, use ```argmax (list) `` `.
