It worked for me as well (R2019a).

Try this:

hl = legend('External Force','Net Force', '$F = \frac{1}{3}$');
set(hl ,'Interpreter','latex')

Answer 1

[Star Strider]

To put a negative sign in front of it, do this:

hl = legend('External Force','Net Force', '$F = -\frac{1}{3}$');
set(hl ,'Interpreter','latex')

If I understand correctly what you want to do.
