DLSODA

 
Solves initial-value problems for stiff and nonstiff systems of ordinary
differential equations. Automatically selects between Adams (nonstiff) and
Backward Differentiation Formula (stiff) methods. In the stiff case, the
Jacobian matrix may be full or banded, and either user-supplied or internally
approximated by difference quotients. Resulting linear systems solved by
direct methods (LU factor/solve). (By: A.C. Hindmarsh and L.R. Petzold).
 
Classes  :  I1a1b . Multistep methods (e.g., Adams predictor-corrector) for
                  general, nonstiff or mildly stiff initial value problems
                  for ordinary differential equations.
            I1a2 .  Stiff and mixed algebraic-ordinary differential
                  equations
