On the computation of accurate initial conditions for linear higher-index differential-algebraic equations and its application in initial value solvers
Michael Hanke, Roswitha März
In contrast to regular ordinary differential equations, the problem of accurately setting initial conditions just emerges in the context of differential-algebraic equations where t…

Towards a reliable implementation of least-squares collocation for higher-index differential-algebraic equations
Michael Hanke, Roswitha März
In this note we discuss several questions concerning the implementation of overdetermined least-squares collocation methods for higher-index differential algebraic equations (DAEs)…
