# VecNestSetSubVecs
Sets the component vectors at the specified indices in a nest vector. 
## Synopsis
```
#include "petscvec.h"   
PetscErrorCode VecNestSetSubVecs(Vec X, PetscInt N, PetscInt *idxm, Vec *sx)
```
Not Collective


## Input Parameters

- ***X  -*** nest vector
- ***N -*** number of component vecs in `sx`
- ***idxm -*** indices of component vectors that are to be replaced
- ***sx -*** array of vectors





## Note
The components in the vector array `sx` do not have to be of the same size as corresponding
components in `X`. The user can also free the array `sx` after the call.
