```python
tensorplay.fft._transforms.fft(input, n=None, dim=-1, norm=None, *, out=None)
```

Computes the one-dimensional discrete Fourier transform.

Parameters:

- input ([Tensor](tensorplay.Tensor.html#tensorplay.Tensor)) – the input tensor

- n ([int](https://docs.python.org/3/library/functions.html#int), optional) – signal length; zero-pads/truncates dim

- dim ([int](https://docs.python.org/3/library/functions.html#int), optional) – the dimension to transform. Default: -1

- norm ([str](https://docs.python.org/3/library/stdtypes.html#str), optional) – "backward", "forward" or "ortho". Default: None (= "backward")
