# TSTrajectorySet
Sets a vector of state in the trajectory object 
## Synopsis
```
#include "petscts.h"  
PetscErrorCode TSTrajectorySet(TSTrajectory tj, TS ts, PetscInt stepnum, PetscReal time, Vec X)
```
Collective


## Input Parameters

- ***tj      -*** the trajectory object
- ***ts      -*** the time stepper object (optional)
- ***stepnum -*** the step number
- ***time    -*** the current time
- ***X       -*** the current solution





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