```python
tensorplay.nn.functional.linear(input: Tensor, weight: Tensor, bias: Tensor | None = None) → Tensor
```

Applies a linear transformation to the incoming data: $y = xA^T + b$.

Shape:

- Input: $(*, H_\text{in})$ where $*$ means any number of dimensions including none and $H_\text{in} = \text{in\_features}$.

- Weight: $(H_\text{out}, H_\text{in})$ where $H_\text{out} = \text{out\_features}$.

- Bias: $(H_\text{out})$

- Output: $(*, H_\text{out})$
