VecStrideMaxAll#
Computes the maximums of subvectors of a vector defined by a starting point and a stride and optionally its location.
Synopsis#
#include "petscvec.h"
PetscErrorCode VecStrideMaxAll(Vec v, PetscInt idex[], PetscReal nrm[])
Collective
Input Parameter#
v - the vector
Output Parameters#
idex - the location where the maximum occurred (not supported, pass
NULL, if you need this, send mail to petsc-maint@mcs.anl.gov to request it)nrm - the maximum values of each subvector
Notes#
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
