- mars.tensor.conj(x, out=None, where=None, **kwargs)¶
Return the complex conjugate, element-wise.
The complex conjugate of a complex number is obtained by changing the sign of its imaginary part.
x (array_like) – Input value.
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 – The complex conjugate of x, with same dtype as y.

>>> x = mt.eye(2) + 1j * mt.eye(2) >>> mt.conjugate(x).execute() array([[ 1.-1.j, 0.-0.j], [ 0.-0.j, 1.-1.j]])
