 a) Verify with numeric applications, 
    some basic properties and theorems I. 
    
 b) This is also an example of the use of the fonctions, 
    I have write.

 c) See your textbook, or ask to your teacher, if you do
    not know how to do the operations.

      Three versions :

    1) The matrices are declared in main() :
    2) The matrices are declared in the functions :
    3) Work with Dev-C++4 and  DJGPP 2.03,
        with your compiler I don't know.
 
    Try the examples in this order.
