# 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.
