# oneHot(withIndicesTensor:depth:axis:name:)

Creates a oneHot operation and returns the result tensor.

## Declaration

```swift
func oneHot(withIndicesTensor indicesTensor: MPSGraphTensor, depth: Int, axis: Int, name: String?) -> MPSGraphTensor
```

## Parameters

- `indicesTensor`: Tensor of indices for on values
- `depth`: Depth of the oneHot vector along the axis
- `axis`: The axis to insert the new oneHot vector at
- `name`: Name for the operation

## Return Value

Return Value A valid MPSGraphTensor object.

## Discussion

Discussion Creates a tensor of rank equal to the rank of indicesTensor + 1, of type MPSDataTypeFloat32. Inserts a new axis at the axis specified, or the minor axis if axis is -1. The values at the indices in the indicesTensor will be set to 1, and all other values will be set to 0.
