For nearly 10 years, I constantly translated my tutorials into English because I found that machine translation tools were not very efficient. This work was very tedious, but I convinced myself that I had to do it. For a year now, I have realized that these tools provide good translations, so much so that I used them directly for the latest English documents I have produced. Under these conditions, it seems more appropriate to me to direct you to
my tutorials in French and advise you to use the online machine translation software.
Thank you very much for all these years of following the publications I have made on this blog. The adventure is not over yet because I still continue, and for a long time I hope, to produce course and tutorial materials for researchers and students.
