Using dynamic subscripts in plot title

I want to use subscripts in a plot title, but the value I want to use changes, depending on the subplot. E.g. If I have 3 subplots (varies) then I want the first plot's title to look like:

title('x_1')

and the second to be:

title('x_2')

etc. I have the value for the subscript in a variable, say i, but how do I set this as a subscript? If I try:

title('x_i')

MatLab interprets the 'i' literally of course. What is the correct way?

Hello, I have a question:

What happens when i > 9?

How to insert subscript two or three symbols?

e.g:

title(' x_1_2 ')

Thank you a lot!
