Hi Venkatesh
The issue lies in the loop where you are updating the sno array. Specifically, the condition (i == sno(i, 1)) is causing the problem. Since sno(i, 1) is always equal to i (due to the assignment inside the loop), the loop becomes infinite.
To rectify this, you can modify the loop as follows:
% Learner phase: To select a student randomly
sno = randi(ns, 1, ns); % Initialize sno without adding 1
% Check that the same student is not selected
for i = 1:ns
while (i == sno(i))
sno(i) = randi(ns); % Update sno directly
end
end
We initialize sno without adding 1 initially, and then directly update its elements within the loop.
Hope this helps!
