                                 The properties of zero matrices :

         pmzaf.c   pmzai.c :       A + 0 =  0 + A
         pmzbf.c   pmzbi.c :       A - A =  0
         pmzcf.c   pmzci.c :       0 - A = -A
         pmzdf.c   pmzdi.c :       A * 0 =  0 * A  = 0

                                 The properties of the transpose : 

         trpaf.c   trpai.c : ( A**T )**T =  A
         trpbf.c   trpbi.c : ( A + B)**T =  A**T + B**T
         trpcf.c   trpci.c : ( A - B)**T =  A**T - B**T
         trpdf.c   trpdi.c : (kA    )**T = kA**T
         trpef.c   trpei.c : (AB    )**T =  B**T * A**T 

                                 The theorem of transpose :
       
       trpinvf.c trpinvi.c :   inv(A**T) = (inv(A))**T

                                 The theorem of inverse matrices :
 
        invabf.c  invabi.c :   inv(AB)   =  inv(B) * inv(A)
