Calculer un vecteur propre :  Permet de calculer le vecteur propre pour la valeur propre "EVALUE".

Exemple de sortie écran :

 A :
  +26191 +1471i    -3444 +9191i   +18535 -3803i 
   -3444 -9191i   +27183 +1470i    -3591 -9206i 
  +18535 +3803i    -3591 +9206i   +29984 +5471i 

 V1 :
 +0.58221-0.15613i      -nan    -nani      -nan    -nani 
 -0.23974-0.38731i      -nan    -nani      -nan    -nani 
 +0.65512+0.00000i      -nan    -nani      -nan    -nani 

Les nan correspondent à la normalisation d'un vecteur nul.
