PETSc version 3.15.5
TSSetCostIntegrand
Sets the routine for evaluating the integral term in one or more cost functions 
Synopsis
#include "petscts.h"  
PetscErrorCode TSSetCostIntegrand(TS ts,PetscInt numcost,Vec costintegral,PetscErrorCode (*rf)(TS,PetscReal,Vec,Vec,void*),
                                                          PetscErrorCode (*drduf)(TS,PetscReal,Vec,Vec*,void*),
                                                          PetscErrorCode (*drdpf)(TS,PetscReal,Vec,Vec*,void*),
                                                          PetscBool fwd,void *ctx)
Logically Collective on TS
Input Parameters
|  | ts | - the TS context obtained from TSCreate() | 
|  | numcost | - number of gradients to be computed, this is the number of cost functions | 
|  | costintegral | - vector that stores the integral values | 
|  | rf | - routine for evaluating the integrand function | 
|  | drduf | - function that computes the gradients of the r's with respect to u | 
|  | drdpf | - function that computes the gradients of the r's with respect to p, can be NULL if parametric sensitivity is not desired (mu=NULL) | 
|  | fwd | - flag indicating whether to evaluate cost integral in the forward run or the adjoint run | 
|  | ctx | - [optional] user-defined context for private data for the function evaluation routine (may be NULL) | 
Calling sequence of rf
  PetscErrorCode rf(TS ts,PetscReal t,Vec U,Vec F,void *ctx);
Calling sequence of drduf
  PetscErroCode drduf(TS ts,PetscReal t,Vec U,Vec *dRdU,void *ctx);
Calling sequence of drdpf
  PetscErroCode drdpf(TS ts,PetscReal t,Vec U,Vec *dRdP,void *ctx);
Notes
For optimization there is usually a single cost function (numcost = 1). For sensitivities there may be multiple cost functions
