mars.tensor.logical_or

mars.tensor.logical_or(x1, x2, out=None, where=None, **kwargs)[source]

Compute the truth value of x1 OR x2 element-wise.

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

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.
