How to continue performing this flowchart about Gauss - Jordan method in a matlab code?

% I'm using matlab to convert this flowchart in a matlab code using "for loop", but I don't know how to continue here in this point. I guess it is possible to use else - if, but I´'m not sure. Please, could you check that?

%Here is the code that I did, but I don't know how to continue:

%Equations SOLVER by Gauss-Jordan METHOD

G=input('Put the n*(n+1) matrix to solve: ');

sz=size(G)

n=sz(1)

for i=1:n

c=G(i,i)

for j=1:n+1

G(i,j)=G(i,j)/c;

end

for k=1:n

That check basically says to skip the first iteration of the loop. You could do this with an if statement and a continue statement, but rather than translate this strictly I'd probably instead just start the loop with k = 2.

% Strict translation with n = 5
for k = 1:5
    if k == 1
        continue
    end
    disp(k)
end

     2

     3

     4

     5

% Looser translation with n = 5
for k = 2:5
    disp(k)
end

     2

     3

     4

     5

If n is less than 2 the loop over k won't do anything anyway, so starting at k = 2 doesn't cause any problems. Neither of the code examples below will display anything (other than the message that the loop is complete, since I wanted to prove to you that the code did in fact run.)

% Strict, n = 1
for k = 1:1
    if k == 1
        continue
    end
    disp(k)
end
disp('For loop #1 complete')

For loop #1 complete

% Loose, n = 1
for k = 2:1
    disp(k)
end
disp('For loop #2 complete')

For loop #2 complete
