equal(x1, x2, out=None, where=None, **kwargs)¶
Return (x1 == x2) element-wise.
- x1, x2 : array_like
- Input tensors 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 array 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.
- For other keyword-only arguments, see the ufunc docs.
- out : Tensor or bool
- Output tensor of bools, or a single bool if x1 and x2 are scalars.

>>> import mars.tensor as mt
>>> mt.equal([0, 1, 3], mt.arange(3)).execute() array([ True, True, False])
What is compared are values, not types. So an int (1) and a tensor of length one can evaluate as True:
>>> mt.equal(1, mt.ones(1)) array([ True])
