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.

$$\text{out}_{i} = conj(\text{input}_{i})$$

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])
