# tensorplay.functional.view_as_real

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

```python
tensorplay.functional.view_as_real(input) → Tensor
```

Returns a view of input as a real tensor. For an input complex tensor of
size $m1, m2, \dots, mi$, this function returns a new
real tensor of size $m1, m2, \dots, mi, 2$, where the last dimension of size 2
represents the real and imaginary components of complex numbers.

> **Warning**
>
> view_as_real() is only supported for tensors with complex dtypes.

Parameters:

input ([Tensor](/docs/generated/tensorplay.Tensor.html#tensorplay.Tensor)) – the input tensor.

Example:

```
>>> x=tensorplay.randn(4, dtype=tensorplay.cfloat)
>>> x
tensor([(0.4737-0.3839j), (-0.2098-0.6699j), (0.3470-0.9451j), (-0.5174-1.3136j)])
>>> tensorplay.view_as_real(x)
tensor([[ 0.4737, -0.3839],
        [-0.2098, -0.6699],
        [ 0.3470, -0.9451],
        [-0.5174, -1.3136]])
```
