A = [11 9 2 47 13 8 9 12];
for i=1:length(A)-1
for j = 2:length(A)
if (A(j-1)> A(j))
temp = A(j-1);
A(j-1) = A(j);
A(j) = temp;
end
end
end
Like given, it is an A vector. And temp is a variable name. It used to calculate sth but it does not tell us what.
I could not get what this code is using for. Can anyone explain it?
