Hi all,

I know how to include variables in title, but is there any way to include variable in title of two lines. I tried to use ({[' ; ']}) with int2str( variable) but it dose not work.

I appreciate your help.

Here's one way:

m = 1;
n = 2;
figure;
plot(1:10)
title({['Line ',num2str(m),' here'];['Line ',num2str(n),' here']})

You can create a text string with sprintf(), then use title() to display it:

caption = sprintf('This image is %s\nIt has %d rows and %d columns',...
  filename, rows, columns);
title(caption, 'FontSize', 30);

The text string can have the regular format specifiers like you're very much used to if you've done any programming before: %s, %.3f, %d, etc. and you can use \n if you want to go to a new line.
