Hi everyone,
I am using the fmincon in matlab to minimize the objective value as
F=-(x(1)^2+x(2)^2+x(3)^2) .
So the objective function I write is
function Fexternal=myfun(x)
x1=x(1);
x2=x(2);
x3=x(3);
Fexternal=-(x1^2+x2^2+x3^2).
x is the 3*1 vector design variable in this problem.
However, there are also some other nonlinear constraints for this problem, i.e.
F1<=120;
F2<=100;
F3<=130;
F4<=140;
F5<=150;
F6<=20.
and F1~F6 are all the functions of the three variables x1~x3,i.e.
F1= F1(x(1),x(2),x(3));
F2= F2(x(1),x(2),x(3));
F3= F3(x(1),x(2),x(3));
F4= F4(x(1),x(2),x(3));
F5= F5(x(1),x(2),x(3));
F6= F6(x(1),x(2),x(3));
They are all long expressions and not simple to write all them explicitly.
How can the nonlinear constraint functions to be written as a .m file?
THX very much for your help!
