-
to_adm
(adj)¶ Return another MultiStageScheme that implements the adjoint linearisation of the ODE solver.
This takes bar{y_n+1} (the derivative of a functional J with respect to y_n+1) and computes bar{y_n} (the derivative of J with respect to y_n).
-
to_tlm
(perturbation)¶ Return another MultiStageScheme that implements the tangent linearisation of the ODE solver.
This takes dot{y_n} (the derivative of y_n with respect to a parameter) and computes dot{y_n+1} (the derivative of y_n+1 with respect to that parameter).
