# 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).
