Computes the minimum of subvector of a vector defined by a starting point and a stride and optionally its location.


#include "petscvec.h" 
PetscErrorCode  VecStrideMinAll(Vec v,PetscInt idex[],PetscReal nrm[])
Collective on Vec

Input Parameter

v -the vector

Output Parameter

idex - the location where the minimum occurred (not supported, pass NULL, if you need this, send mail to [email protected] to request it)
nrm - the minimums of each subvector


One must call VecSetBlockSize() before this routine to set the stride information, or use a vector created from a multicomponent DMDA.

The dimension of nrm must be the same as the vector block size
