How to insert loop variable inside plot label?
显示 更早的评论
I want to insert the value of the loop variable inside a label next to a string. How do I do it?
for i = 1:n
subplot(1,n,i)
plot(1:m,THETA(i,:))
hold on
plot(1:m+1,THETA_est_rls(i,:))
plot(1:m+1,THETA_est_ewrls(i,:))
legend('true','RLS','EWRLS')
xlabel('Iterations');
ylabel('\theta', i);

I assume you want to include it in your ylabel call.
This works:
ylabel(sprintf('\\theta %d', i));
The double \\ are necessary to get one of them to print correctly. (The leading \ operates as an ‘escape’ character.)

As always, my pleasure!
If you want the index ‘i’ to appear as a subscript instead, this works:
ylabel(sprintf('\\theta_{%d}', i));

For the cap, yes.
ylabel(sprintf('$\\hat{\\theta}_{%d}$', i), 'Interpreter','latex');
