VecAXPBYPCZ#
Computes z = alpha x + beta y + gamma z
Synopsis#
#include "petscvec.h"
PetscErrorCode VecAXPBYPCZ(Vec z, PetscScalar alpha, PetscScalar beta, PetscScalar gamma, Vec x, Vec y)
Logically Collective
Input Parameters#
alpha - first scalar
beta - second scalar
gamma - third scalar
x - first vector
y - second vector
z - third vector
Output Parameter#
z - output vector
Note#
x, y and z must be different vectors
Developer Notes#
The implementation is optimized for alpha of 1.0 and gamma of 1.0 or 0.0
