# TSSundialsSetMaxl
Sets the dimension of the Krylov space used by GMRES in the linear solver in `TSSUNDIALS`. `TSSUNDIALS` DOES NOT use restarted GMRES so this is the maximum number of GMRES steps that will be used. 
## Synopsis
```
#include "petscts.h" 
PetscErrorCode TSSundialsSetMaxl(TS ts, PetscInt maxl)
```
Logically Collective


## Input Parameters

- ***ts      -*** the time-step context
- ***maxl -*** number of direction vectors (the dimension of Krylov subspace).
