VecStrideMinAll#

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

Synopsis#

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

Collective

Input Parameter#

  • v - the vector

Output Parameters#

  • idex - the location where the minimum occurred (not supported, pass NULL, if you need this, send mail to petsc-maint@mcs.anl.gov to request it)

  • nrm - the minimums 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
