# replacing(atIndices:with:alongAxis:)

Replaces slices along the specified indices with the given replacement values.

## Declaration

```swift
func replacing(atIndices indices: MLTensor, with replacement: some MLTensorScalar, alongAxis axis: Int) -> MLTensor
```

## Parameters

- `indices`: A 32-bit integer tensor containing indices to scatter values from replacement. indices must have the same shape as self except at axis. Must be in the range [-rank, rank).
- `replacement`: The replacement value.
- `axis`: The axis to scatter to.

## Return Value

Return Value The updated tensor.

## Discussion

Discussion For example: let x = MLTensor(shape: [2, 3], scalars: [     10, 30, 20,     60, 40, 50 ], scalarType: Float.self) let i = MLTensor(shape: [2, 1], scalars: [     1,     0 ], scalarType: Int32.self) let y = x.replacing(with: 99, atIndices: i, alongAxis: 1) // [[10, 99, 20], //  [99, 40, 50]]
