#include "petscts.h" PetscErrorCode TSTrajectoryGetUpdatedHistoryVecs(TSTrajectory tj, TS ts, PetscReal time, Vec *U, Vec *Udot)Collective on TSTrajectory
| tj | - the TS trajectory context | |
| ts | - the TS solver context | |
| time | - the requested time |
| 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().
