numpy.ma.MaskedArray.argmax¶

MaskedArray.argmax(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 alongthe specified axis fill_value : {var}, optional Value used to fill in the masked values. If None, the output ofmaximum_fill_value(self._data) is used instead. out : {None, array}, optional Array into which the result can be placed. Its type is preservedand 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])
