On commence par calculer les variables libres.

Les colonnes de b_free sont une base pour le complément orthogonal de A. 

         A * b_free = 0

Cela prouve que les vecteurs lignes de A sont orthogonaux aux vecteurs colonnes de b_free. 


Exemple de sortie écran :

 ------------------------------------ 
Find a basis for the orthogonal complement of A :

 A :
 +2 -1i  -6 +2i  -7 -6i  -6 +6i  +7 +8i 
 +9 -9i  -2 +6i  +1 -6i  +2 +5i  -7 -1i

 -1 -3i  +3 +7i  +8 +7i  +6 -7i  -9 +7i 

 b :
 +0 +0i 
 +0 +0i 
 +0 +0i 
 +0 +0i 

 Ab :
