Thank you so much. But I am not able to extract it. Is there any other way?

[Mohd Sufian]

You can easily extract it by using 7zip or WINRAR on windows

for 7zip you have to extract it 2 time

A=[1 1 1; 2 1 3; 3 4 -2]; 
B=[4;7;9]; 
n=length(B);
Aug= [A B]
for i=1:n
    Aug(i,:)=Aug(i,:)./Aug(i,i);
    for j=1:n
        if j~=i
            key1=Aug(j,i)./Aug(i,i);
            Aug(j,:)=Aug(j,:)-key1.*Aug(i,:); 
        end 
    end 
end
fprintf('Solution of the given system \n');
disp(Aug(:,end)

Have you tried it? There's nothing here that's Octave-specific. For sake of making the solution unique-valued, I'm going to tweak the inputs.

% slightly modified inputs
A = [1 1 1; 2 1.5 3; 3 4 -2]; 
B = [4;7;9]; 

n = length(B); 
Aug = [A B];
for i = 1:n
    Aug(i,:) = Aug(i,:)./Aug(i,i);
    for j = 1:n 
        if j ~= i 
            key1 = Aug(j,i)./Aug(i,i); 
            Aug(j,:) = Aug(j,:) - key1.*Aug(i,:); 
        end
    end
end

% this is a clumsy way to display it here, but okay
fprintf('Solution of the given system \n')

Solution of the given system 

disp(Aug(:,end))

   -3.0000
    5.3333
    1.6667

Of course, this whole thing isn't necessary unless you were told to solve it that way. See mldivide, \

% same thing
A = [1 1 1; 2 1.5 3; 3 4 -2]; 
b = [4;7;9]; 
x = A\b % solve

x = 3×1

-3.0000 5.3333 1.6667
