How can I use the num2str command in the latex interpreter?

Hi all,

I'm currently creating a function which plots a transfer function based on what values the user has given. In the title of the plot I added the transfer function as a fraction using the the latex interpreter command, however I'd like the coefficients that the user selected to be shown on my transfer function. I've tried using the num2str command in place of the coefficients however I'm getting errors all over the place.

Any help would be appreciated

users coeffients
d1 = 1
d2 = 10
d3 = 4

% Title
  title('Untit step response of $G(s) = \displaystyle\frac{4}{d1s^2+d2s+d3}$','interpreter','latex')

I managed to solve the problem myself, what I did was to add ',num2str(x),' to where I wanted my coefficients.
