numpy.ma.MaskedArray.argmax
method
-
MaskedArray.argmax(self, axis=None, fill_value=None, out=None)
[source] -
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])
