Fmincon two variables

WebApr 10, 2024 · In fact, objective function only includes two variables that are x (1) and x (2). Therefore, how does this code ("Fmincon") work? I have not found the similar question in the community. Could anyone explain it or share the relevant link? Many thanks in advance! Sign in to comment. Sign in to answer this question. I have the same question (0) WebDec 21, 2024 · The reason is that with fmincon you have to put all of the control variables into one vector, typically called x. This x would contain both HatAlpha and HatC. With the problem-based approach, you are free to use the variables that are most natural for your problem.

WebThe fmincon function takes several arguments, including the objective function, the initial guess for the variables, the inequality constraints, the bounds, and several optional arguments that control the optimization process. In this example, we use the 'sqp' algorithm for optimization and display the optimization progress using the 'iter' option.

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 (). eku deans

WebSkip to content WebApr 10, 2024 · Answers (1) fmincon takes the size of the x0 input as determining the number of input variables. 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.
