WebFeb 6, 2015 · You need to learn about variables in/out functions. Practically in any programming language, when you enter a function, that function can only access the variables that are created inside, or that are passed as an argument as x, y, z and potato in the next example: myfun(x,y,z, potato).. This means that in:

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. ctsb armyWebJul 26, 2024 · Accepted Answer: Walter Roberson I have two objective functions which would optimize same variables.
