vSgemx(_:_:_:_:_:_:)

Declaration

func vSgemx(_ m: Int32, _ n: Int32, _ alpha: Float, _ a: UnsafePointer<vFloat>, _ x: UnsafePointer<vFloat>, _ y: UnsafeMutablePointer<vFloat>)

Parameters

• m:

  Number of rows in a, and the length of vector y; must be a multiple of 4.

• n:

  Number of columns in a, and the length of vector x; must be a multiple of 4.

• alpha:

  Scalar multiplier for matrix a.

• a:

  m by n matrix with elements of type float.

• x:

  Vector with elements of type float.

• y:

  Destination vector with n elements of type float.

Discussion

Matrix a is multiplied by alpha and then by vector x; the resulting vector is added to vector y, and the results are stored in y.
