Diagonal approximation of Jacobians by difference quotients.
val solver :
('data, 'kind) Cvode.session_linear_solver
A linear solver based on Jacobian approximation by difference quotients.
val get_work_space :
('d, 'k) Cvode.session -> int * int
Returns the sizes of the real and integer workspaces used by the Diagonal linear solver.
val get_num_rhs_evals :
('d, 'k) Cvode.session -> int
Returns the number of calls made to the right-hand side function due to finite difference Jacobian approximation in the Diagonal linear solver.
