While the formula is correct, the MATLAB code provided works well for scalar values but requires element-wise operations when working with matrices. By default, MATLAB assumes matrix operations on the variables. To address the warning encountered, the code should be modified as follows:
% Note element-wise operations
hill = @(S,Vmax,K,n) Vmax .* S.^n ./ (K.^n + S.^n);
% Check Michaelis-Menten Function using S, Vmax=1, Km=0.1, and n=1
hill_1 = @(S) hill(S, 1, 0.1, 1);
% Plot the function
figure(1)
fplot(hill_1, [0, 3])

Hope this helps.
