To simulate the KSE, I have used a famous software : MATLAB. So it
rid me of the choise of the inversion method of matrix and of the
postprocessor treatment of the results.
The suject of this project is not a numerical method, I just tried to
determinate some bifurcations in the KSE.
The Matlab script of the function I have writen to simulate the KSE is in appendix (see A).
