Test computation using the GUI
==================================================================================
----------------------------------------------------------------------------------
Test computation of a functional of the geopotential:
----------------------------------------------------------------------------------

Panel GEOPOTENTIAL MODEL AND REFERENCE SYSTEM SELECTION

- Import the enclosed GGM file "EGM96.mat" using the "Browse..." button.

Panel POINT TYPE SELECTION

- Select the checkbox "Load data" and click the "Browse..." button (next to the checkbox) 
  to import the enclosed input test file "input.txt".

Panel CALCULATED PARAMETERS AND OUTPUT SELECTION

- In the first pop-up menu, choose "Disturbing_potential". 
- Enter the name of the output file using the button "Output folder and file"
  (enter only the name of the file, i.e. without any suffix).
- Click the "OK" button to start the computational process.

Compare the computed results with the results in the enclosed sample output file "output_EGM96.txt".


----------------------------------------------------------------------------------
Test computation of a commission error:
----------------------------------------------------------------------------------

Panel GEOPOTENTIAL MODEL AND REFERENCE SYSTEM SELECTION

- Import the enclosed file of error variance-cavariance matrix "GRIM5C1_covmat.mat" using the 
  "Browse..." button.
- Set the nmin value to 2.

Panel POINT TYPE SELECTION

- Select the checkbox "Load data" and click the "Browse..." button (next to the checkbox) 
  to import the enclosed input test file "input.txt".

Panel CALCULATED PARAMETERS AND OUTPUT SELECTION

- Select the checkbox "Commission error".
- In the first pop-up menu, choose "Disturbing_potential". 
- Enter the name of the output file using the button "Output folder and file"
  (enter only the name of the file, i.e. without any suffix).
- Click the "OK" button to start the computational process.

Compare the computed results with the results in the enclosed sample output file "output_GRIM5C1.txt".

Test computation without using the GUI
==================================================================================
The aforementioned test computation can be run completely without using the GUI via
the command:

GrafLab('OK',3986004.415E+8,6378136.3,0,360,1,'EGM96.mat',0,1,[],[],[],[],[],[],[],'input.txt',[],[],[],'output',0,5,1,[],1,1,0,[],[],[],[],[],1)

The description of the input variables can be found in the source code (look for the text:
"function GrafLab")
