Synopsis
#include "petscvec.h"
PetscErrorCode VecMin(Vec x,PetscInt *p,PetscReal *val)
Collective on Vec
Input Parameters
x -the vector
Output Parameter
| val | - the minimum component
|
| p | - the location of val (pass PETSC_NULL if you don't want this location)
|
Notes
Returns the value PETSC_MAX_REAL and p = -1 if the vector is of length 0.
This returns the smallest index with the minumum value
