Descriptor Systems

Just like time-delay systems, descriptor systems are also fully integrated into Mathematica.

    
Obtain a descriptor state-space model from a differential-algebraic equation:

If the descriptor matrix is nonsingular the system can be converted to a standard state-space representation:
