BVNormVec
Computes the norm of a given vector. 
Synopsis
#include "slepcbv.h" 
PetscErrorCode BVNormVec(BV bv,Vec v,NormType type,PetscReal *val)
Collective on BV
Input Parameters
|  | bv | - basis vectors | 
|  | v | - the vector | 
|  | type | - the norm type | 
Output Parameter
Notes
This is the analogue of BVNormColumn() but for a vector that is not in the BV.
If a non-standard inner product has been specified with BVSetMatrix(),
then the returned value is sqrt(v'*B*v), where B is the inner product
matrix (argument 'type' is ignored). Otherwise, VecNorm() is called.
