Linear systems toolbox: system analysis and control design in the matlab environment

The software package linear system toolbox in Matlab is described. The Linear Systems Toolbox is aimed at providing some commonly used system analysis functions which are either not available or not reliable in other software packages. This tool box contains about 50 functions. It includes, among other functions, the computation of geometric subspaces and the invariant zeros, the inner-outer factorization of a linear system, the determination of the infinite zero structures, Morse's and Saberi's indices and strong stability, and the solutions to the decoupling and squaring down problems. Some examples are included to demonstrate the use of the tool box.<
