VecPointwiseMult#

Computes the component-wise multiplication w[i] = x[i] * y[i].

Synopsis#

#include "petscvec.h"   
PetscErrorCode VecPointwiseMult(Vec w, Vec x, Vec y)

Logically Collective

Input Parameters#

x - the first vector
y - the second vector

Output Parameter#

w - the result

Note#

Any subset of the x, y, and w may be the same vector.
