# vSswap(_:_:_:)

Interchanges the elements of two vectors.

## Declaration

```swift
func vSswap(_ n: Int32, _ x: UnsafeMutablePointer<vFloat>, _ y: UnsafeMutablePointer<vFloat>)
```

## Parameters

- `n`: Number of elements in vectors x and y; must be a multiple of 4.
- `x`: Vector with n elements of type float.
- `y`: Vector with n elements of type float.

## Discussion

Discussion Each element of vector x is replaced by the corresponding element of y, and vice versa.
