:orphan: # TSAdjointMonitorDrawSensi Monitors progress of the adjoint `TS` solvers by calling `VecView()` for the sensitivities to initial states at each timestep ## Synopsis ``` #include "petscts.h" PetscErrorCode TSAdjointMonitorDrawSensi(TS ts, PetscInt step, PetscReal ptime, Vec u, PetscInt numcost, Vec *lambda, Vec *mu, void *dummy) ``` Collective ## Input Parameters - ***ts -*** the `TS` context - ***step -*** current time-step - ***ptime -*** current time - ***u -*** current state - ***numcost -*** number of cost functions - ***lambda -*** sensitivities to initial conditions - ***mu -*** sensitivities to parameters - ***dummy -*** either a viewer or `NULL` ## See Also [](ch_ts), `TSAdjointSolve()`, `TSAdjointMonitorSet()`, `TSAdjointMonitorDefault()`, `VecView()` ## Level intermediate ## Location src/ts/interface/sensitivity/tssen.c --- [Edit on GitLab](https://gitlab.com/petsc/petsc/-/edit/release/src/ts/interface/sensitivity/tssen.c) [Index of all Sensitivity routines](index.md) [Table of Contents for all manual pages](/manualpages/index.md) [Index of all manual pages](/manualpages/singleindex.md)
