CAS routines for theoretical analysis of nonlinear time-delay systems
SAC (Symbolic Analysis and Control) is a toolbox for people working in control theory. It will help to the analysis and synthesis of nonlinear systems described by state equations (with or without delays).
KHorn is a universal easy to use CAS (Computer Algebra System). It will be usable for Physics, Chemistry, Mathematics and other natural sciences. KHorn is based on the GMP library.
