Hello all, Please I am new to the optimization field. I have an ode system which I have solved and have performed parameter estimation, I am at the steady state optimization step but I do not know how to use fmincon for this purpose. I solved the ODE model using euler explicit method and used EKF for the parameter estimation. My system is my non-linear equality constraint. I want to optimize my input using the parameters I estimated, for solving the ODE my input and uncertain parameters are constant, but I am made to understand that they have to be changing for the optimization step at each Iteration.

I have tried to read https://www.mathworks.com/help/optim/ug/nonlinear-equality-and-inequality-constraints.html and also watch some examples online but all contain just regular equations. Please I need help. I have attached my codes for clarity.
