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 +2 +5
v_T :
+3 +4 +1
w_T :
+5 +1 +3
u x (v+w) == (uxv) + (uxw)
u x (v+w) :
-17 +24 +4
(uxv) + (uxw) :
-17 +24 +4
Press return to continue.
