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 ().

WebApr 5, 2024 · You CANNOT use fmincon on a problem with binary variables or any form of discrete variables. However, IF y is indeed binary, then you have only two cases to consider. So solve the problem to minimize f (x), given y == 0, and then repeat, solving it for the minimum over x of f (x), given y == 1. Take the better of the two results and you are … WebJan 31, 2013 · I just saw in your code you want to pas in two extra parameters, X and Y.

How to use fmincon as fminbd with two different variables

WebApr 29, 2024 · Answers (1) fmincon is not going to pass two fun two separate parametrs, x1 and x2, corresponding to the three different values in x0. Instead, it is going to pass fun a single vector of three values. fun can, if it wants, pull those out into seperate variables for clearer coding. Likewise, the nonlinear constraint function is not going to be ... 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.

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.
