Fmincon two variables

WebApr 15, 2016 · Hello, I have a question about defining nonlinear inequality constraints for 'fmincon' function. With the example in document, it seems there can only be 1 equality and 1 inequality constraint function [c,ceq] = circlecon(x) 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. Good luck, Alan Weiss MATLAB mathematical toolbox documentation on 2 Mar …

WebOct 3, 2024 · using the eigenvalue with the largest absolute value is potentially discontinuous in the variables. fmincon requires differentiable jacobian but anything equivalent to a max() operation is not differentiateable at the boundary (and the jacobian potentially turns into zero with respect to some of the variables.) 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.

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 (). WebAug 17, 2024 · One option would be to do a variable transformation in your objective function. So for example, instead of making x your optimizing variable, use y, which we define as: y = x if 0<100, and y = x+30 if -100<-30. Note that, for allowable values of x, y ranges from -70 to +100, so you'd want to make those the constraints for y in fmincon.
