# tensorplay.functional.movedim

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

```python
tensorplay.functional.movedim(input, source, destination) → Tensor
```

Moves the dimension(s) of input at the position(s) in source
to the position(s) in destination.

Other dimensions of input that are not explicitly moved remain in
their original order and appear at the positions not specified in destination.

Parameters:

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

- source ([int](https://docs.python.org/3/builtins/functions.html#int) or [tuple](https://docs.python.org/3/builtins/stdtypes.html#tuple) of ints) – Original positions of the dims to move. These must be unique.

- destination ([int](https://docs.python.org/3/builtins/functions.html#int) or [tuple](https://docs.python.org/3/builtins/stdtypes.html#tuple) of ints) – Destination positions for each of the original dims. These must also be unique.

Examples:

```
>>> t = tensorplay.randn(3,2,1)
>>> t
tensor([[[-0.3362],
        [-0.8437]],

        [[-0.9627],
        [ 0.1727]],

        [[ 0.5173],
        [-0.1398]]])
>>> tensorplay.movedim(t, 1, 0).shape
tensorplay.Size([2, 3, 1])
>>> tensorplay.movedim(t, 1, 0)
tensor([[[-0.3362],
        [-0.9627],
        [ 0.5173]],

        [[-0.8437],
        [ 0.1727],
        [-0.1398]]])
>>> tensorplay.movedim(t, (1, 2), (0, 1)).shape
tensorplay.Size([2, 1, 3])
>>> tensorplay.movedim(t, (1, 2), (0, 1))
tensor([[[-0.3362, -0.9627,  0.5173]],

        [[-0.8437,  0.1727, -0.1398]]])
