WebJun 20, 2016 · You won't be able to use fmincon () because it doesn't handle integer arguments. You need a solver for 'mixed integer programming', which involves arguments that take both real and integer values. If you can formulate your problem as a mixed integer linear program (which doesn't appear to be the case), then you can use intlinprog (). WebNonlinear constraints allow you to restrict the solution to any region that can be described in terms of smooth functions. Nonlinear inequality constraints have the form c(x) ≤ 0, where c is a vector of constraints, one component for each constraint. Similarly, nonlinear equality constraints have the form ceq(x) = 0. curly cat

Your x0 has 6 elements, so fmincon thinks that you have a 6-variable problem. You are attempting to vectorize fmincon. However, fmincon cannot be vectorized, meaning it does not accept multiple input points.
