TSAdjointSolve

Solves the discrete ajoint problem for an ODE/DAE

Synopsis

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

Collective `

Input Parameter

• ts - the TS context obtained from TSCreate()

Options Database Key

• -ts_adjoint_view_solution - views the first gradient with respect to the initial values

Notes

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
