reciprocal(x, out=None, where=None, **kwargs)¶
Return the reciprocal of the argument, element-wise.
- x : array_like
- Input tensor.
- 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.
- y : Tensor
- Return tensor.
This function is not designed to work with integers.
For integer arguments with absolute value larger than 1 the result is always zero because of the way Python handles integer division. For integer zero the result is an overflow.
>>> import mars.tensor as mt
>>> mt.reciprocal(2.).execute() 0.5 >>> mt.reciprocal([1, 2., 3.33]).execute() array([ 1. , 0.5 , 0.3003003])
