VecSetValuesCOO#

set values at once in a vector preallocated using VecSetPreallocationCOO()

Synopsis#

#include "petscvec.h"   
PetscErrorCode VecSetValuesCOO(Vec x, const PetscScalar coo_v[], InsertMode imode)

Collective

Input Parameters#

  • x - vector being set

  • coo_v - the value array

  • imode - the insert mode

Note#

The values must follow the order of the indices prescribed with VecSetPreallocationCOO() or VecSetPreallocationCOOLocal(). When repeated entries are specified in the COO indices the coo_v values are first properly summed, regardless of the value of imode. The imode flag indicates if coo_v must be added to the current values of the vector (ADD_VALUES) or overwritten (INSERT_VALUES). VecAssemblyBegin() and VecAssemblyEnd() do not need to be called after this routine. It automatically handles the assembly process.
