MINLP with equality constrains

How can I solve a MINLP problem with equality constraints? I use the "ga" function and the optimization tool, without obtaining favorable results.

Your code uses fmincon, not ga. fmincon will definitely not let you impose integer constraints.

Hi, thank you very much for the answer, I refer the .m file of the "ga" function, so Matlab cannot solve MINLP problems with equality constraints?
