numpy.ma.argmax¶
-
numpy.ma.
argmax
(self, axis=None, fill_value=None, out=None) = <numpy.ma.core._frommethod object>¶ Returns array of indices of the maximum values along the given axis. Masked values are treated as if they had the value fill_value.
Parameters: axis : {None, integer}
If None, the index is into the flattened array, otherwise along the specified axis
fill_value : {var}, optional
Value used to fill in the masked values. If None, the output of maximum_fill_value(self._data) is used instead.
out : {None, array}, optional
Array into which the result can be placed. Its type is preserved and it must be of the right shape to hold the output.
Returns: index_array : {integer_array}
Examples
>>> a = np.arange(6).reshape(2,3) >>> a.argmax() 5 >>> a.argmax(0) array([1, 1, 1]) >>> a.argmax(1) array([2, 2])
