Les vecteurs en mathématiques sont supposés être des vecteurs colonnes, c'est pour cela que j'utilise _T pour afficher des vecteurs lignes.


Exemple de sortie écran :

  u_T  :
  -4 -1i   -4 +3i   +9 -9i 

  v_T  :
  +6 +3i   -6 -5i   -7 -5i 

  w_T  :
  +3 -9i   +5 +5i   +1 -9i 



    u  x (v+w) == (uxv) + (uxw) 

    u  x (v+w) :
  +75+29i   +17-197i   +22-50i 

 (uxv) + (uxw) :
  +75+29i   +17-197i   +22-50i
