Hello,

I am a begginer in Matlab and I'm trying to solve the maximization problem below,

I looked up some simple code that I tried to adapt but I think the problem is in how I can't find a way to define parameters as constants and i get an error everytime I try to run the code I'm trying to use (below, with incorrect definition of parameters)

t = [];

h = [];

b = [];

e = [];

l = [];

m = [];

F = [];

f = [];

s = [];

p = optimvar('p');

q = optimvar('q');

a = optimvar('a');

prob = optimproblem;

prob.Objective = (p - (t*q^l/h))*q^{s-1}*a^{s-1}*(p^{-s}/(P^{1-s}))*Y - f * (a^(1-e)/(1+e)) - F * q^b;

prob.Constraints.cons1 = m*((p - (1-d)*(tq^(l)/h))*(q*a)^(s-1)*(p^(-s)/(P^(1-s)))*Y - (1-d)*f*(a^(1-e)/(1+e)) - F*q^b) >= d*(((tq^(l)/h))*(q*a)^(s-1)*(p^(-s)/(P^(1-s)))*Y - f*(a^(1-e)/(1+e)) - F*q^b);

sol = solve(prob);

My question is, how can I define the parameters as just constant parameters?

You should to define your parameters as constrains (equality, inequality or non-linear) and based on that, you should to define de O.F. You must to select the optimization solver.
