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
