# expandingShape(at:)

Returns a new shaped array with expanded dimensions.

## Declaration

```swift
func expandingShape(at axis: Int) -> MLShapedArray<Scalar>
```

## Discussion

Discussion The shape of the new MLShapedArray gets a new dimension of 1 at the specified axis index. let original = MLShapedArray<Int32>(scalars: 0..., shape: [2, 3]) let expanded = original.expandingShape(at: 0) expanded.shape // [1, 2, 3]
