VecMaxPointwiseDivide#
Computes the maximum of the componentwise division max = max_i abs(x_i/y_i).
Synopsis#
#include "petscvec.h"
PetscErrorCode VecMaxPointwiseDivide(Vec x, Vec y, PetscReal *max)
Logically Collective on x
Input Parameters#
x, y - the vectors
Output Parameter#
max - the result
Notes#
x and y may be the same vector
if a particular y_i is zero, it is treated as 1 in the above formula
