VecPointwiseDivide#
Computes the component-wise division w[i] = x[i] / y[i].
Synopsis#
#include "petscvec.h"
PetscErrorCode VecPointwiseDivide(Vec w, Vec x, Vec y)
Logically Collective
Input Parameters#
x - the numerator vector
y - the denominator vector
Output Parameter#
w - the result
Note#
Any subset of the x, y, and w may be the same vector.
