Vote 0. Answered: Alan Weiss on 7 Apr I need to solve an optimization problem with two nonlinear equality constraints.

My function evaluation is very fast less than a second and I also provide fmincon with the gradients of my objective and constraint functions. However, when fmincon is slow when there are about variables, and it is very slow when there are variables.

Considering my function evaluation is super fast, I guess the bottle neck is the speed of fmincon. Based on your location, we recommend that you select:. Select the China site in Chinese or English for best site performance.

Using fmincon for optimization, when having too many variables. But some of the variables should be chosen as constant. Thus, the variables should change into their values set by the user in objective function decreasing the variable number. If he set only one of them, then fmincon can solve for the other. And how to change variables into constant values. As a first glance fmincon optimize the function and give 4 vraiables as x vector.
