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
|
A :
|
+4 +2 +5
|
+4 +2 +5
|
+3 +4 +1
|
| 1 1 1 | | u1 u2 u3 |
|
u.(u x v) == u. | u1 u2 u3 | == | u1 u2 u3 | == det(A)
|
| v1 v2 v3 | | v1 v2 v3 |
|
u.(u x v) == det(A) == +0.0000
