compute a weighted 2norm of the difference between two state vectors
Synopsis
#include "petscts.h"
PetscErrorCode TSErrorWeightedNorm2(TS ts,Vec U,Vec Y,PetscReal *norm,PetscReal *norma,PetscReal *normr)
Collective on TS
Input Arguments
 ts   time stepping context

 U   state vector, usually ts>vec_sol

 Y   state vector to be compared to U

Output Arguments
norm weighted norm, a value of 1.0 means that the error matches the tolerances
norma weighted norm based on the absolute tolerance, a value of 1.0 means that the error matches the tolerances
normr weighted norm based on the relative tolerance, a value of 1.0 means that the error matches the tolerances
