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!
