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
