GAMMA Base Demo 1
(Γ Version 4.0.4β)
 

 
Simple I/O & GAMMA Matrix
This program uses only a simple matrix and some standard output. No input is required. Have a quick look at the source code (demo1.cc). All it does is make a matrix and then write it to the screen.

The expected output will look like the following: 

   Hello World
             
   The Matrix I Just Made: GAMMA 4 x 4 Diagonal Matrix
             
             (  4.00 ,  0.00)
                   (  4.00 , 0.00)
                         (  4.00 , 0.00)
                               (  4.00 , 0.00)

Compiling Demo 1
The executable program can be generated from the shell prompt by invoking the C++ compiler with the proper arguments. There is a prepared script file, gamma which contains the proper call to the compiler with library links, etc. This assumes that you have a working GNU C++ on your system, a compiled GAMMA library with headers (>= Version 3.5) and an accesible gamma command.

To compile the program issue the command (where the command start gamma1:ssmith> is my system prompt)

gamma1:ssmith>gamma demo1.cc

The following is the dialog one might expect from this compilation 

gamma1:ssmith>gamma demo1.cc


               G  A  M  M  A
                                 
               (Version 3.5)

The Compilation Is Specific To sun4

This will produce the executable program named (by default) a.out on a Unix/Linux system and a.exe by default under WinTel.

Executing Demo 1
The executable program (a.out or a.exe) can be now be run by issuing the command a.out in the command window. 
gamma1:ssmith>a.out
No input arguments are required and the output has been shown at the top of this page.
