# tensorplay.functional.complex

Source: https://www.tensorplay.cn/docs/generated/tensorplay.functional.complex.html

```python
tensorplay.functional.complex(real, imag, *, out=None) → Tensor
```

Constructs a complex tensor with its real part equal to [real](/docs/generated/tensorplay.functional.real.html#tensorplay.functional.real) and its
imaginary part equal to [imag](/docs/generated/tensorplay.functional.imag.html#tensorplay.functional.imag).

Parameters:

- real ([Tensor](/docs/generated/tensorplay.Tensor.html#tensorplay.Tensor)) – The real part of the complex tensor. Must be half, float or double.

- imag ([Tensor](/docs/generated/tensorplay.Tensor.html#tensorplay.Tensor)) – The imaginary part of the complex tensor. Must be same dtype as [real](/docs/generated/tensorplay.functional.real.html#tensorplay.functional.real).

Keyword Arguments:

out ([Tensor](/docs/generated/tensorplay.Tensor.html#tensorplay.Tensor)) – If the inputs are tensorplay.float32, must be
tensorplay.complex64. If the inputs are tensorplay.float64, must be
tensorplay.complex128.

Example:

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