VecMin

 Determines the vector component with minimum real part and its location.

Synopsis

#include "petscvec.h"   
PetscErrorCode  VecMin(Vec x,PetscInt *p,PetscReal *val)
Collective on Vec

Input Parameter

x - the vector

Output Parameters

p - the location of val (pass NULL if you don't want this location)
val - the minimum component

Notes

Returns the value PETSC_MAX_REAL and negative p if the vector is of length 0.

This returns the smallest index with the minumum value
