# reverse(_:)

Reverses a vector of single-precision values in-place.

## Declaration

```swift
static func reverse<V>(_ vector: inout V) where V : AccelerateMutableBuffer, V.Element == Float
```

## Parameters

- `vector`: The vector that the function reverses.

## Discussion

Discussion The single- and double-precision reverse(_:) functions reverse the elements of an array. The following code reverses the elements in the array values: var values: [Float] = [9, 8, 7, 6, 5, 4, 3, 2, 1, 0]

vDSP.reverse(&values)

// Prints "[0.0, 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0]". print(values)
