PetscErrorCode VecNormEnd(Vec x, NormType ntype, PetscReal *result)

x - the first vector
ntype - norm type, one of
NORM_1,NORM_2,NORM_MAX,NORM_1_AND_2result - where the result will go
Notes#
Each call to VecNormBegin() should be paired with a call to VecNormEnd().
The x vector is not allowed to be NULL, otherwise the vector would not have its correctly cached norm value
