# mean(keepRank:)

Returns the mean along all axes.

## Declaration

```swift
func mean(keepRank: Bool = false) -> MLTensor
```

## Parameters

- `keepRank`: A Boolean indicating whether to keep the reduced axes or not. The default value is false.

## Return Value

Return Value The reduced tensor.

## Discussion

Discussion For example: let x = MLTensor(shape: [3, 2], scalars: [2, 3, 4, 5, 6, 7], scalarType: Float.self) let y = x.mean() y.shape // is [] await y.shapedArray(of: Float.self) // is [4.5]
