L'affichage des vecteurs d'une colonne prend trop de place. J'ai donc tenté de les installer dans une matrice avant de les afficher.

Exemple de sortie écran :

 -------------------------------
 The Three Standard Columns Vectors 

   A[0]     A[1]     A[2] :
  +1 +0i   +0 +0i   +0 +0i   +0 +0i 
  +0 +0i   +1 +0i   +0 +0i   +0 +0i 
  +0 +0i   +0 +0i   +1 +0i   +0 +0i 

 Press return to continue. 


 -------------------------------
 V is a linear combination of    
 the three Standard Columns Vectors of R_3 :

    z0*A[0]    z1*A[1]    z2*A[2]  =  V 
    +8 -6i     -0 +0i     +0 +0i     +8 -6i 
    +0 +0i     -8 +6i     +0 +0i     -8 +6i 
    +0 +0i     -0 +0i     +4 -5i     +4 -5i
