A DESCRIPTOR SYSTEMS Toolbox for MATLAB

Abstract: The recently developed PERIODIC SYSTEMS Toolbox for MATLAB is de-scribed. The basic approach to develop this toolbox was to exploit the powerful object ma-nipulation features of MATLAB via exible and functionally rich high level m-functions, while simultaneously enforcing highly efcient and numerically sound computations via the mex-function technology of MATLAB to solve critical numerical problems. The m-functions based user interfaces ensure user-friendliness in operating with the functions of this toolbox via an object oriented approach to handle periodic system descriptions. The mex-functions are based on FORTRAN implementations of recently developed structure exploiting and structure preserving numerical algorithms for periodic systems which completely avoid forming of lifted representations.
