LAX-backend implementation of argmax().

Original docstring below.

  • a (array_like) – Input array.

  • axis (int, optional) – By default, the index is into the flattened array, otherwise along the specified axis.


index_array – Array of indices into the array. It has the same shape as a.shape with the dimension along axis removed. If keepdims is set to True, then the size of axis will be 1 with the resulting array having same shape as a.shape.

Return type

ndarray of ints
