Parameters ---------- x1, x2 : array_like Logical OR is applied to the elements of `x1` and `x2`. They have to be of the same shape. out : Tensor, None, or tuple of Tensor and None, optional A location into which the result is stored. If provided, it must have a shape that the inputs broadcast to. If not provided or `None`, a freshly-allocated tensor is returned. A tuple (possible only as a keyword argument) must have length equal to the number of outputs. where : array_like, optional Values of True indicate to calculate the ufunc at that position, values of False indicate to leave the value in the output alone. **kwargs Returns ------- y : Tensor or bool Boolean result with the same shape as `x1` and `x2` of the logical OR operation on elements of `x1` and `x2`. See Also -------- logical_and, logical_not, logical_xor bitwise_or Examples -------- >>> import mars.tensor as mt >>> mt.logical_or(True, False).execute() True >>> mt.logical_or([True, False], [False, False]).execute() array([ True, False]) >>> x = mt.arange(5) >>> mt.logical_or(x < 1, x > 3).execute() array([ True, False, False, False, True]) """ op = TensorOr(**kwargs) return op(x1, x2, out=out, where=where)
