Using \cdot in sprintf, with latex interpreter

set(0, 'defaultTextInterpreter', 'latex');

text(160, 1, (sprintf("$ i(t) = %g \cdot (1 - e^{-t/%g})$", iF, tau)),...

'Fontsize', 15)

This text is for a subtitle on a subplot. The "set interpreter latex" is at the beginning of my code because I need to use it multiple times. I need \cdot to display as a multiplication sign in the subtile. What its displaying right now is this, i(t) = 5 i(t) = 25 .

text(0.5, 8, (sprintf("i(t) = %g \\cdot (1 - e^{-t/%g})", 1, 2)),'Fontsize', 15)

This should do it for you.

Keep the $ characters.
