Matlab optimization problem

I have a optimization problem to solve in Matlab. A lot of the work is already done for this first part. Biggest issue is to correct mistakes. I and sending you the photos of the problem atached and also the code i have done so far. I will explain here exactly what has to be done(i dont know a lot of matlab so may be hard to explain sorry) The point os to optimize the target function using the function fmincon The decision valiable is a vector X that includes 4 vector inside Q1 Q2 V1 and V2. Q1 and A2 are constant. V1 and V2 are calculated. I will explain the functions i already did (some have mistakes): calcX0 - calculates the initial vector that will be used to optimize parteX - divides the entrance vector X in the 4 subvectors to be used in other functions juntaX - joins the 4 sub vectors back to X dados - inicializes the given values for the problem calcr - calculates the value of R that depends on H and deltaH (giving errors) calch - calculates h calcdeltah- calculates delta h LB are the lower bounds from the restrictions UB are the upper bounds for the restrictions restricoes is where all the restrictions of the problem should be The problem is about a hidro electric power station so thats why there are 2 different stations (and 2 R's and delta h and so on) Completo is still empty but thats where i should calculate the target of the problem and optimize it using the function fmincon Fmincon final should be something like this: fmincon(X0,LB,UB,fobj,restricoes) The info and code is atached as [login to view URL] If you have any doubts feel free to contact me. This is the first step of a bigger problem and i am willing to pay well for someone that will be interested in doing the full project if this first step goes well. Thanks a lot
