TSTrajectoryGetVecs#
Reconstructs the vector of state and its time derivative using information from the TSTrajectory and, possibly, from the TS
Synopsis#
#include "petscts.h"
PetscErrorCode TSTrajectoryGetVecs(TSTrajectory tj, TS ts, PetscInt stepnum, PetscReal *time, Vec U, Vec Udot)
Collective on TS
Input Parameters#
tj - the trajectory object
ts - the time stepper object (optional)
stepnum - the requested step number
Input/Output Parameter#
Output Parameters#
time - On input time for the step if step number is PETSC_DECIDE, on output the time associated with the step number
U - state vector (can be NULL)
Udot - time derivative of state vector (can be NULL)
Notes: If the step number is PETSC_DECIDE, the time argument is used to inquire the trajectory. If the requested time does not match any in the trajectory, Lagrangian interpolations are returned.
