Abstract
This paper presents experiences in numerical computing the index of differential-algebraic equations during simulation. Based on the tractability index a program INDEX has been created. The index definition and the algorithms via matrix orthogonalization and singular value decomposition respectively are given. Areas of application and test results from the usage of the program at a large variety of examples are reported, experiences are discussed.
