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.
