VecAXPBY#
Computes y = alpha x + beta y.
Synopsis#
#include "petscvec.h"
PetscErrorCode VecAXPBY(Vec y, PetscScalar alpha, PetscScalar beta, Vec x)
Logically Collective on Vec
Input Parameters#
alpha,beta - the scalars
x, y - the vectors
Output Parameter#
y - output vector
Notes#
x and y MUST be different vectors The implementation is optimized for alpha and/or beta values of 0.0 and 1.0
