# vSrot(_:_:_:_:_:)

Applies planar rotation to a set of n points whose x and y coordinates are contained in two arrays of vectors.

## Declaration

```swift
func vSrot(_ n: Int32, _ x: UnsafeMutablePointer<vFloat>, _ y: UnsafeMutablePointer<vFloat>, _ c: Float, _ s: Float)
```

## Parameters

- `n`: Number of points to be rotated; must be a multiple of 4.
- `x`: Vector with n/4 elements of type vector float, representing the x-coordinates of the points.
- `y`: Vector with n/4 elements of type vector float, representing the y-coordinates of the points.
- `c`: Cosine of the angle of rotation.
- `s`: Sine of the angle of rotation.

## Discussion

Discussion The coordinates are modified in place in the vectors in arrays x and y.
