VecZeroEntries

puts a 0.0 in each element of a vector

Synopsis

#include "petscvec.h"   
PetscErrorCode  VecZeroEntries(Vec vec)
Logically Collective on Vec

Input Parameter

vec -The vector

Developer Note: This routine does not need to exist since the exact functionality is obtained with VecSet(vec,0); I guess someone added it to mirror the functionality of MatZeroEntries() but Mat is nothing like a Vec (one is an operator and one is an element of a vector space, yeah yeah dual blah blah blah) so this routine should not exist.

Keywords

Vec, set, options, database
