 The main functionalities of the toolbox include:
 
-    * similarity and equivalence transformations for standard and descriptor systems
-       - essential computations with structured matrices, including
-       - eigenvalues of a Hamiltonian matrix or of a skew-Hamiltonian/Hamiltonian pencil
-       - Periodic Hessenberg and periodic Schur decompositions
-    * computations with (block) Toeplitz matrices and systems
-    * analysis of standard and descriptor systems
-    * solution of Lyapunov and Riccati equations with condition estimation
-    * coprime factorization and spectral decomposition of transfer-function matrices
