Calculer un vecteur propre : Permet de calculer le vecteur propre pour la valeur propre "EVALUE".
Exemple de sortie écran :
A :
+26191 +1471i -3444 +9191i
-3444 -9191i +27183 +1470i
V1 :
-0.24181+0.64521i -nan -nani
+0.72473+0.00000i -nan -nani
Les nan correspondent à la normalisation d'un vecteur nul.
