# torch.complex

torch.complex(real, imag, *, out=None) → Tensor

  Constructs a complex tensor with its real part equal to `real` and its imaginary part equal to `imag`.

  Parameters:

    - real (Tensor) – The real part of the complex tensor. Must be half, float or double.

    - imag (Tensor) – The imaginary part of the complex tensor. Must be same dtype as `real`.

  Keyword Arguments:

    out (Tensor) – If the inputs are `torch.float32`, must be `torch.complex64`. If the inputs are `torch.float64`, must be `torch.complex128`.

  Example:

      >>> real = torch.tensor([1, 2], dtype=torch.float32)
      >>> imag = torch.tensor([3, 4], dtype=torch.float32)
      >>> z = torch.complex(real, imag)
      >>> z
      tensor([(1.+3.j), (2.+4.j)])
      >>> z.dtype
      torch.complex64
