ScicosLab is the new name of ScilabGtk. This change of name has been decided in order to avoid all confusion with Scilab, which is no longer developed at INRIA. ScicosLab is developed by some of the researchers who originally developed Scilab at INRIA and ENPC. ScicosLab is used in particular for disributing new software developments stemming from research activities of the Metalau team at INRIA and ENPC, such as Scicos (Scicos 4.3 in ScicosLab 4.3) and the Maxplus algebra toolbox.
