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. inception msci worldWebApr 10, 2024 · Answers (1) fmincon takes the size of the x0 input as determining the number of input variables.
