#include "petscts.h" PetscErrorCode TSSetRHSFunction(TS ts,Vec r,PetscErrorCode (*f)(TS,PetscReal,Vec,Vec,void*),void *ctx)Logically Collective on TS
| ts | - the TS context obtained from TSCreate() | |
| r | - vector to put the computed right hand side (or NULL to have it created) | |
| f | - routine for evaluating the right-hand-side function | |
| ctx | - [optional] user-defined context for private data for the function evaluation routine (may be NULL) |
func (TS ts,PetscReal t,Vec u,Vec F,void *ctx);
| t | - current timestep | |
| u | - input vector | |
| F | - function vector | |
| ctx | - [optional] user-defined function context |
Notes: You must call this function or TSSetIFunction() to define your ODE. You cannot use this function when solving a DAE.
