Compiling symbolic computations Matlab 2016a

Hello All,

does anybody know how can I compile a GUI using the following symbolic computation:

syms I D T; % Define symbolic variables

Model = (k*T^a/D^b); % Create symbolic equation

fprintf('The Model is I = %s = (mm/min)\n',char(Model));

Plot_Str = latex(I == (k*T^a) / (D^b));

handles.Plot_Str = ['$$' Plot_Str '$$'];

however, I am getting the following error:

undefined function or variable syms matlab gui

is there any alternative way to do this in Matlab R2016a? ... without using the symbolic math toolbox,

thanks in advance !
