Hi all, I am trying to perform multi objective optimization and this is my function
f
unction [y, cons] = TMS_CONSTR_objfun(x)
y = [0 0];
cons = [];
x(1:10)=1;
d(1:10)=0;
sp(1:10)=0;
y(1)=sum(x(1:10));
for h=1:10
d(h)=x(h)*xe(h);
sp(h)=x(h)*ve(h);
end
dd=d(d~=0);
spp=sp(sp~=0);
n=length(dd);
for j=2:n-1 y(2)=abs(((dd(1)+dd(2))/(2*spp(1)))+9.7-((x(n)+x(n-1))/(2*spp(n))+ sum((x(j+1)-x(j-1))/(2*spp(j))))); end
I keep received an error: Undefined function or variable 'x'.
why?

Hi Adam
It seems that you are executing the nonlinear function itself. If that is the case, I wonder what is the expected answer? Also, would you let me know what is the output cons for?
if you want to optimize this function, you need to use one of the optimization solvers in MATLAB, such as fmincon and fminsearch. The documentations are given as below:
