TSTrajectoryGetUpdatedHistoryVecs#
Get updated state and time-derivative history vectors.
Synopsis#
#include "petscts.h"  
PetscErrorCode TSTrajectoryGetUpdatedHistoryVecs(TSTrajectory tj, TS ts, PetscReal time, Vec *U, Vec *Udot)
Collective
Input Parameters#
- tj - the - TSTrajectorycontext
- ts - the - TSsolver context
- time - the requested time 
Output Parameters#
- U - state vector at given time (can be interpolated) 
- Udot - time-derivative vector at given time (can be interpolated) 
Notes#
The vectors are interpolated if time does not match any time step stored in the TSTrajectory(). Pass NULL to not request a vector.
This function differs from TSTrajectoryGetVecs() since the vectors obtained cannot be modified, and they need to be returned by
calling TSTrajectoryRestoreUpdatedHistoryVecs().
