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 Type : Fortran subroutine in SODEPACK package. Access : Public domain. Portable. Precision: Single.
