scilab 5.3.3-10ubuntu2 (i386 binary) in ubuntu quantal

 Scilab is a matrix-based scientific software package.
 Scilab contains hundreds of built-in mathematical functions, rich
 data structures (including polynomials, rationals, linear systems, lists,
 etc...) and comes with a number of specific toolboxes for control, signal
 processing, ...
 .
 This package also provides Xcos, a graphical editor to design hybrid
 dynamical systems models. Models can be designed, loaded, saved, compiled and
 simulated.
 Stable and efficient solution for industrial and academics needs, Xcos
 provides functionalities for modeling of mechanical systems (automotive,
 aeronautics...), hydraulic circuits (dam, pipe modeling...), control systems,
 etc. Modelica capabilities are also provided.
 .
 Scilab is one of the most credible alternatives to Matlab and Simulink.
 .
 For a minimum version of scilab, install package "scilab-cli".
