# vSnaxpy(_:_:_:_:_:) Performs the computation of `vSaxpy` `n` times, using a different multiplier each time. ``` func vSnaxpy(_ n: Int32, _ m: Int32, _ a: UnsafePointer, _ x: UnsafePointer, _ y: UnsafeMutablePointer) ``` ## Parameters `n` Number of elements in vector `a`; must be a multiple of 4. `m` Number of elements in each of the vectors `x` and `y`; must be a multiple of 4. `a` A vector array of `float` values. `x` A second vector array of `float` values. `y` A second vector array of `float` values. ## Discussion For i = 0 to n-1, the elements of `x` are multiplied by `a`[i] and added to the corresponding elements of `y`. The results are accumulated and stored in `y`. --- Copyright © 2026 Apple Inc.
