# vSscal(_:_:_:)

Scales a vector in place.

## Declaration

```swift
func vSscal(_ n: Int32, _ alpha: Float, _ x: UnsafeMutablePointer<vFloat>)
```

## Parameters

- `n`: Number of elements in vector x; must be a multiple of 4.
- `alpha`: Scaling factor.
- `x`: Vector with n elements of type float.

## Discussion

Discussion Each element of vector x is multiplied in place by alpha.
