# torch.conj_physical

torch.conj_physical(input, *, out=None) → Tensor

  Computes the element-wise conjugate of the given `input` tensor. If `input` has a non-complex dtype, this function just returns `input`.

  Note

  This performs the conjugate operation regardless of the fact conjugate bit is set or not.

  Warning

  In the future, `torch.conj_physical()` may return a non-writeable view for an `input` of non-complex dtype. It’s recommended that programs not modify the tensor returned by `torch.conj_physical()` when `input` is of non-complex dtype to be compatible with this change.

  out i=c o n j(input i)\text{out}_{i} = conj(\text{input}_{i}) out i​=co nj(input i​)
  Parameters:

    input (Tensor) – the input tensor.

  Keyword Arguments:

    out (Tensor, optional) – the output tensor.

  Example:

      >>> torch.conj_physical(torch.tensor([-1 + 1j, -2 + 2j, 3 - 3j]))
      tensor([-1 - 1j, -2 - 2j, 3 + 3j])
