  La fonction trace se contente d'additionner tous les coefficients sur la diagonale.

Exemple de sortie écran :

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

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



 Trace(AB) = -316 -4i 


 Trace(BA) = -316 -4i
