TSErrorWeightedNorm2

compute a weighted 2-norm 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
