# 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
