# argsort(alongAxis:descendingOrder:)

Returns the indices (or arguments) of a tensor that give its sorted order along the specified axis.

## Declaration

```swift
func argsort(alongAxis axis: Int = -1, descendingOrder: Bool = false) -> MLTensor
```

## Parameters

- `axis`: The axis along which to sort. The default is -1, which sorts the last axis.
- `descendingOrder`: A Boolean value that determines the sort order. The default is false which sorts from largest to least.

## Return Value

Return Value A Int32 tensor of sorted indices.

## Discussion

Discussion For example: let x = MLTensor([1.0, 3.0, 2.0]) let y = x.argSort() await y.shapedArray(of: Int32.self) // is [0, 2, 1]
