How to use function file

%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);

[Jan]

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

thanks for the help.

Minimize e

subject to

e+x_{i} -0.5 >= 0 , i member of {1,2,3}

e+x_{1}+ x_{i} -1.25 >= 0 , i member of {2,3}

e+x_{2}+ x_{3}-1 >= 0 ,

x_{1}+x_{2}+x_{3}= 1.75

x_{i}- 0.5 >= 0 i member of {1,2,3}

I want to compute x_{1},x_{2} and x_{3} when is at its minimum e=0

Can you help me with this
