I have a problem with this file that I have wrote it

clear
fid=fopen ('dusss.txt');
A=fscanf(fid,'%g%g%g%g',[4 inf]);
fclose(fid);
clc
B=load('dusss.txt');

for i=1:17;
Result(i,1)=B(i,2)+B(i,3)+B(i,4);

if Result(i,1)>79
G(i,1)=A;
elseif Result(i,1)>74
G(i,1)=3.5;
elseif Result(i,1)>69
G(i,1)=3;
elseif Result(i,1)>64
G(i,1)=2.5;
elseif Result(i,1)>59
G(i,1)=2;
elseif Result(i,1)>54
G(i,1)=1.5;
elseif Result(i,1)>49
G(i,1)=1;
else
G(i,1)=0;
end


end
S=[B Result G];
disp(' code F.test S.test Final test total Grade')
disp(' 30% 15% 50% 100%')
disp(S)


When I run this file why the result be like this

Look up help on the following commands: format, int8, int16, int32, uint8, uint16 and uint32.

You basically have an issue with formatting of the displayed output.

if you use the "format long g" command you will allow the full double precision values to be displayed, rather than the truncated values you see. Also, your first column appears to be an integer value (I'm not sure), and if so, you may want to convert the value to integer before displaying it.

 

Note, you may also want to look into the sprintf and fprintf commands which allow printing to files and to strings with better formatting control. Just dumping an array to the screen is somewhat limited. The issue is that your first column has so many numbers, and the other columns don't.
