As part of the French STI reform and for teaching engineering sciences in preparatory classes for the grandes écoles, Scilab Enterprises provides teachers with free open source tools.

Scilab

Scilab is free open source software for numerical computation which includes hundreds of mathematical functions. It has a high level programming language allowing access to advanced data structures, 2-D and 3-D graphical functions. 

Xcos

Freely available and distributed with Scilab, Xcos is a graphical editor to design hybrid dynamical systems models. Models can be designed, loaded, saved, compiled and simulated.

Modules

• CPGE
  CPGE module allows to model control systems and perform time and frequency simulations (Bode, Black and Nyquist diagrams...).
• Coselica
  Coselica module provides about 200 basic Xcos Modelica blocks for modeling and simulation of electrical (analog), mechanical (1D-translational, 1D-rotational, and 2D-planar) and thermodynamical (0/1D-heattransfer) systems.
• NIDAQ
  The NIDAQ module allows to connect Scilab to NI Instrumentation Device
  You can:
  • Read data in Scilab for immediate analysis,
  • Send data over analog and digital output channels provided by the instrumentation device,
  • Control analog input and output, counter/timer and digital I/O DAQ device (National Instruments).
