# SNESLineSearchGetVecs
Gets the vectors from the `SNESLineSearch` context 
## Synopsis
```
#include "petscsnes.h" 
PetscErrorCode SNESLineSearchGetVecs(SNESLineSearch linesearch, Vec *X, Vec *F, Vec *Y, Vec *W, Vec *G)
```
Not Collective on but the vectors are parallel


## Input Parameter

- ***linesearch -*** linesearch context



## Output Parameters

- ***X -*** Solution vector
- ***F -*** Function vector
- ***Y -*** Search direction vector
- ***W -*** Solution work vector
- ***G -*** Function work vector





## Notes
At the beginning of a line search application, `X` should contain a
solution and the vector `F` the function computed at `X`.  At the end of the
line search application, `X` should contain the new solution, and `F` the
function evaluated at the new solution.

These vectors are owned by the `SNESLineSearch` and should not be destroyed by the caller
