%Fitness function

function y=myFitness(u)

y=0.004*u(1)-0.0031*u(2)+0.0075*u(3)+0.0015*u(4)-0.0086*u(5)+0.0077*u(6)+0.0060*u(7)-0.0060*u(8)-0.0011*u(9)+0.0093*u(10);

end

I have a code that calculate the co-efficient of u(1) to u(10). i want to change the co-efficient of u(1) to u(10) at every time steps before executing the main.m

main.m

ObjFcn=@myFitness;

nvars=10;

LB= [0 0 0 0 0 0 0 0 0 0];

UB=[500 600 120 180 60 80 30 50 30 50];

[u,fval]=ga(ObjFcn,nvars,[],[],[],[],LB,UB);

在 MATLAB Online 中打开

function y = myFitness(u, c)
y = c * u(:); 
end
function main
c = [0.004, -0.0031, 0.0075, 0.0015, -0.0086, 0.0077, 0.0060, -0.0060, ...
    -0.0011, 0.0093];
ObjFcn = @(u) myFitness(u, c);
nvars  = 10;
LB     = [0 0 0 0 0 0 0 0 0 0];
UB     = [500 600 120 180 60 80 30 50 30 50];
[u, fval] = ga(ObjFcn, nvars, [], [], [], [], LB, UB);
c = c + 0.01;  % Or what ever the change should look like
ObjFcn = @(u) myFitness(u, c);
[u, fval] = ga(ObjFcn, nvars, [], [], [], [], LB, UB);
... etc
