# tensorplay.functional.broadcast_to

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

```python
tensorplay.functional.broadcast_to(input, shape) → Tensor
```

Broadcasts input to the shape shape.
Equivalent to calling input.expand(shape). See expand() for details.

Parameters:

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

- shape (list, tuple, or [tensorplay.Size](/docs/generated/tensorplay.Size.html#tensorplay.Size)) – the new shape.

Example:

```
>>> x = tensorplay.tensor([1, 2, 3])
>>> tensorplay.broadcast_to(x, (3, 3))
tensor([[1, 2, 3],
        [1, 2, 3],
        [1, 2, 3]])
```
