Overview

daeIndexDet stands for Index Determination in DAEs and is a program for computing the index in systems of differential algebraic equations (DAEs) with properly stated leading terms. Its current version is coded in C++.

daeIndexDet uses the indexdet library, which actually provides the functionalities for the index computation by using Automatic Differentiation techniques. These techniques provide an efficient calculation of machine-precision, accurate derivatives via truncated Taylor series arithmetic.
