Solves linearly-implicit initial-value problems for stiff and nonstiff systems of ordinary differential equations. Both Adams (nonstiff), and Backward Differentiation Formula (stiff) methods are used. All matrices are assumed to be block-tridiagonal, and the Jacobian may be either user-supplied or internally approximated. The resulting linear systems solved by direct methods (LU factor/solve). (By: A.C. Hindmarsh and C.S. Kenney). 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.
