The package includes a computation of all the local invariants of the
, system, a regularization procedure and an index reduction scheme and
, it can be combined with every solution method for standard index 1
, systems. Nonuniqueness and inconsistencies are treated in a least
, square sense. In our package we have implemented backward
, differentiation formulas (BDF) methods and Runge-Kutta schemes.
