La fonction M_mulC_mZ(); multiplie une colonne par z.

Exemple de sortie écran :

 A : 

   -4 -2i    -1 -9i    -2 +4i    +9 -1i    -9 -4i 
   -8 +5i    -8 -1i    -5 -3i    +1 +3i    -8 +1i 
   +5 +4i    +7 -1i    +3 -3i    +4 +3i    +1 -9i 
   -1 -1i    +3 -6i    +1 -8i    +5 -4i    -6 +6i 

 multiply column C3 by +100+0i 


 A : 

   -4  -2i    -1  -9i  -200+400i    +9  -1i    -9  -4i 
   -8  +5i    -8  -1i  -500-300i    +1  +3i    -8  +1i 
   +5  +4i    +7  -1i  +300-300i    +4  +3i    +1  -9i 
   -1  -1i    +3  -6i  +100-800i    +5  -4i    -6  +6i
