Change spacing between title lines

I have a multi-line title I'm trying to change the spacing between. The first line is size 14 font, the second line is size 10 font. The gap between the lines feels especially big. Any thoughts or suggestions on how to correct this? Code provided below.

t = title({['\fontsize{14}','Line 1']; ...
    ['\fontsize{10}',sprintf('Line 2',variable)]}, ...
    'FontWeight','Normal');

Amongst anything else,

sprintf('Line 2',variable)

isn't valid syntax; missing a format expression for a variable which is undefined/unknown in isolation...

It doesn't seem that big to me. Any less and it would be too crowded

plot([0 1]) % Create axes with a plot in it.
[t, s] = title('Line 1 is the main title','Line 2 is the subtitle','Color','blue');
t.FontSize = 14; % Set main title font.
s.FontSize = 10; % Set subtitle font.

In your exercise, one of the viable solutions is to create one necessarily formatted blank line between the two lines.
