DASSL is designed for the numerical solution of implicit systems of differential/algebraic equations written in the form F(t,y,y')=0, where F, y, and y' are vectors, and initial values for y and y' are given. Systems of differential/algebraic equations (DAE) arise in several diverse applications in the physical world. Problems of this type occur frequently in the numerical method-of-lines treatment of partial differential equations, in the simulation of electronic circuits, where they are sometimes called semistate equations, and in the dynamic analysis of mechanical systems. These problems can all be solved using DASSL. Both a single-precision version (SDASSL) for long word-length machines and a double-precision version (DDASSL) for short word-length machines are included.
