Abstract :
This is the manual for the code DGENDA Version 1.0. DGENDA solves initial value problems for general nonlinear differentiell algebraic equations (DAEs) (of arbitrary index) in the form F(t,x(t),x'(t))=0, with initial condition x_0. DGENDA uses a BDF method with order and stepsize control and is implemented in FORTRAN 77.
