# vSrot(_:_:_:_:_:) Applies planar rotation to a set of n points whose x and y coordinates are contained in two arrays of vectors. ``` func vSrot(_ n: Int32, _ x: UnsafeMutablePointer, _ y: UnsafeMutablePointer, _ 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 The coordinates are modified in place in the vectors in arrays `x` and `y`. --- Copyright © 2026 Apple Inc.
