Use a numerical computation software After 1980 1980: Matlab written in Fortran and public domain 1984: creation of The MathWorks company Since 1990: Matlab is the standard and a monopoly Around 1980: Blaise then Basile built upon Matlab 1990: creation of Scilab at INRIA 1994: Scilab freely distributed on the net History
6
From 1994 to present : Path to success 1994: Scilab freely distributed on the net 2003 : Consortium creation at INRIA 12 Members : Axs Ingénierie, Cril Technology, CEA, CNES, Dassault Aviation, EDF, ENPC, Esterel Technologies, INRIA, PSA Peugeot Citroën, Renault et Thales From 2003 to 2007 : Growing partnership 25 Members : Ecole Centrale Paris, Ecole Polytechnique, Enpc, Anagram Technologies, Appedge, Artenum, Axs Ingenierie, Atmel Roma, Engnet, Klippel, Mandriva, Scaleo Chip, Styrel Technologies, Tni, Esterel Technologies, Cea, Cnes, Dassault Aviation, Eads, Edf, Ifp, Inria, Psa Peugeot Citroën, Renault, Thales 2008 to … : Integrate of the Digiteo research network Major objectives : Strive for excellence Integrate recent research outcomes Expand the community of contributors Develop a powerful open source ecosystem Consolidate the operation at the European and international level.
