When using gnat, the commands to check that you are starting right are:

                                            gnatk8 name on DOS
  gcc -c int_io.ads
  gcc -c define_real.ads                    defireal.ads
  gcc -c real_io.ads
  gcc -c real_matrix_arithmetic.ads         rematari.ads
  gcc -c real_matrix_arithmetic.adb         rematari.adb
  gcc -c matrix_demo.adb                    matrdemo.adb
  gnatbl matrix_demo.ali                    matrdemo.ali
  matrix_demo                               go32 matrdemo.exe

The results should be:

 DUMP OF MAT_1A 
MAT(  0,  0 ) = -1.10000E+00
MAT(  0,  1 ) =  1.20000E+00
MAT(  0,  2 ) =  1.30000E+00
MAT(  0,  3 ) =  1.40000E+00
MAT(  1,  0 ) =  2.10000E+00
MAT(  1,  1 ) =  2.20000E+00
MAT(  1,  2 ) =  2.30000E+00
MAT(  1,  3 ) =  2.40000E+00
MAT(  2,  0 ) =  3.10000E+00
MAT(  2,  1 ) =  3.20000E+00
MAT(  2,  2 ) =  3.30000E+00
MAT(  2,  3 ) =  3.40000E+00
 DUMP OF MAT_3 := MAT_1 * MAT_2 
MAT( -2,  5 ) =  1.30000E+01
MAT( -2,  6 ) =  1.35000E+01
MAT( -1,  5 ) =  2.30000E+01
MAT( -1,  6 ) =  2.39000E+01
MAT(  0,  5 ) =  3.30000E+01
MAT(  0,  6 ) =  3.43000E+01
matricies not compatable for requested operation



For Homework 5, add a function to add matricies to Real_Matrix_Arithmetic

Then add declarations of MAT_4 and MAT_5 to Matrix_Demo
     also add initial values for MAT_4

Remove comments in Matrix_Demo as indicated to compute and print MAT_5

NOTE: Although Ada allows the definition of operators as overloaded
      functions, there is no provision for changing operator precedence.
      The precedence will be as shown in ISO 8652:1995 4.5
