# TSTrajectoryGet
Updates the solution vector of a time stepper object by querying the `TSTrajectory` 
## Synopsis
```
#include "petscts.h"  
PetscErrorCode TSTrajectoryGet(TSTrajectory tj, TS ts, PetscInt stepnum, PetscReal *time)
```
Collective


## Input Parameters

- ***tj      -*** the trajectory object
- ***ts      -*** the time stepper object
- ***stepnum -*** the step number



## Output Parameter

- ***time    -*** the time associated with the step number





## Note
Usually one does not call this routine, it is called automatically during `TSSolve()`
