   Scilab is a scientific software package for numerical computations in a user-friendly environment. It features:

   • Matlab-like syntax.
   • Stunning graphics (2d, 3d, animation).
   • Open structure (easy interfacing with Fortran and C via online dynamic link).
   • Linear Algebra (including sparse matrices, Kronecker form, ordered Schur,...).
   • Control (Classical, LQG, H-infinity,...).
   • Package for LMI (Linear Matrix Inequalities) optimization.
   • Signal processing.
   • Simulation (various ode's, dassl,...).
   • Optimization (differentiable and non-differentiable, LQ solver).
   • Scicos, an interactive environment for modeling and simulation of hybrid systems.
   • Metanet (network analysis and optimization).
   • Symbolic capabilities through Maple interface.
