# tensorplay.functional.angle

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

```python
tensorplay.functional.angle(input: Tensor, *, out: Tensor | None) → Tensor
```

Computes the element-wise angle (in radians) of the given input tensor.

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

Parameters:

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

Keyword Arguments:

out ([Tensor](/docs/generated/tensorplay.Tensor.html#tensorplay.Tensor), optional) – the output tensor.

zero for non-negative real numbers, and propagates NaNs. Previously
the function would return zero for all real numbers and not propagate
floating-point NaNs.

Example:

```
>>> tensorplay.angle(tensorplay.tensor([-1 + 1j, -2 + 2j, 3 - 3j]))*180/3.14159
tensor([ 135.,  135,  -45])
```
