TSAdjointSolve

Solves the discrete ajoint problem for an ODE/DAE

#include "petscts.h"  
PetscErrorCode TSAdjointSolve(TS ts)

Collective on TS

ts -the TS context obtained from TSCreate()

-ts_adjoint_view_solution <viewerinfo> -views the first gradient with respect to the initial values

This must be called after a call to TSSolve() that solves the forward problem

By default this will integrate back to the initial time, one can use TSAdjointSetSteps() to step back to a later time
