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,beta, gamma - the scalars
x, y, z - the vectors
Output Parameter#
z - output vector
Note#
x
, y
and z
must be different vectors
Developer Note#
The implementation is optimized for alpha of 1.0 and gamma of 1.0 or 0.0
