Algorithm 658_ ODESSA - An ordinary differential equation solver with explicit simultaneous sensitivity analysis. ODESSA is a package of FORTRAN routines for simultaneous solution of ordinary differential equations and the associated first-order parametric sensitivity equations, yielding the ODE solution vector below;(t) and the first-order sensitivity coefficients with respect to equation parameters below;. ODESSA is a modification of the widely disseminated initial-value solver LSODE, and retains many of the same operational features. Standard program usage and optional capabilities, installation, and verification considerations are addressed herein. (Source: http://dl.acm.org/)
