Test computation using the GUI ================================================================================== Panel GEOPOTENTIAL MODEL AND REFERENCE SYSTEM SELECTION - Import the enclosed GGM file "EGM96.mat" using the "Browse..." button. Panel IRREGULAR SURFACE SELECTION - Click the "Browse..." button to import the enclosed input test file "input.txt". This file contains ellipsoidal heights (in metres) of the computational points at irregular surface. - Use the following values to define the grid: Lat. min (°) = 48 Lat. step (°) = 1 Lat. max (°) = 49 Lon. min (°) = 20 Lon. step (°) = 1 Lon. max (°) = 22 Height above the reference surface (m) = 0 Panel CALCULATED PARAMETERS AND OUTPUT SELECTION - In the first pop-up menu, choose "Disturbing_potential". - Enter 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.txt". ================================================================================== Test computation without using the GUI ================================================================================== The aforementioned test computation can be run completely without using the GUI via the command: isGrafLab('OK',3986004.415E+8,6378136.3,0,360,1,'EGM96.mat',0,3,48,1,49,20,1,22,0,'input.txt',0,'my_output',5,1,[],1,1,0,[],[],[],[],[],1) The description of the input variables can be found in the source code (look for the text: "function isGrafLab") ==================================================================================
