Returns the indices of
the maximum values along an axis.
Parameters: a : array_like Input array. axis : int, optional By
default, the index is into the flattened array, otherwise along the
specified axis. out : array, optional If provided, the result will be
inserted into this array. It should be of the appropriate shape and
dtype. Returns: index_array : ndarray of ints Array of indices into
the array. It has the same shape as a.shape with the dimension along
axis removed. See also ndarray.argmax, argmin
amax The maximum value along a given axis. unravel_index Convert a
flat index into an index tuple. Notes
In case of multiple occurrences of the maximum values, the indices
corresponding to the first occurrence are returned.

a = [1, -3, -10, 3]
