Solves initial-value problems for stiff and nonstiff systems of ordinary differential equations. Both Adams (nonstiff), and Backward Differentiation Formula (stiff) methods are used. In the stiff case, it treats the Jacobian matrix in general sparse form, with the sparsity structure determined on its own or by the user. The Yale Sparse Matrix Package is used to solve the linear systems that arise. (By: A.C. Hindmarsh and A.H. Sherman). 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.
