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 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
