La fonction mulC_mZ(); multiplie la colonne c par un complexe z.

Exemple de sortie écran :

 A : 

   +1 +1i    +2 +1i    +3 +1i 
   +1 +1i    +2 +1i    +3 +1i 
   +1 +1i    +2 +1i    +3 +1i 

 multiply column C2 by +10+0i 


 A : 

   +1 +1i   +20+10i    +3 +1i 
   +1 +1i   +20+10i    +3 +1i 
   +1 +1i   +20+10i    +3 +1i
