Genetic Algorithms LOTS OF ERROR HELP HELP HELP

Hello Everyone!

I'm new to matlab and I'm working on getetic algorithms my fitness function is:

y = (a(1,i)*(1-exp(-b(i)*T(i)))) + (a(2,i)*(1-(1+b(i)*T(i))*exp(-b(i)*T(i)))) + (a(3,i)*(1-(1+ b(i)*T(i)+((b(i)*T(i))^2)/2)*exp(-b(i)*T(i))));

AND I write it in editor in this way:

function y = m(a,b,T)
a=[313,332,298;107,97,64;81,76,32];

b=[0.00368,0.00234,0.0018];

T=zeros(1,3); %Initilization of T with zeros

for i=1:3
y = (a(1,i)*(1-exp(-b(i)*T(i)))) + (a(2,i)*(1-(1+b(i)*T(i))*exp(-b(i)*T(i)))) + (a(3,i)*(1-(1+ b(i)*T(i)+((b(i)*T(i))^2)/2)*exp(-b(i)*T(i))));

T(:,i);
end

My constraint function

is shown in picture and I wrote it in this way:

function [c,ceq] = mrc(C,m) 
C=[5,5,5;10,10,10;15,15,15]

m=zeros(3,3)
R=zeros(1,3)
l;

for v = 1:3 
c = [
T(v)- 5000;
2.7- R(v);
C(1)(v)*m(1)(v)*T(v) + C(2)(v)*m(2)*T(v) + C(3)(v)*m(3)(v)*T(v)-10000;
]
end
ceq = [];

The input parameters are shown in image:

Where variables denote:

There are lots and lots of error some of them are: *()-indexing must appear last in an index expression.(constraint function) *Cannot access T(3) Because value of T(2) is .......(fitness function) *not enough input parameter(IN ga tool box)

Output must look like:

Every help would be appreciated for any other detail please email me to [e-mail] Please help I really need it and if you were able to get the same output as shown in picture that would be great! send me the code too :P

Your line

C(1)(v)*m(1)(v)*T(v) + C(2)(v)*m(2)*T(v) + C(3)(v)*m(3)(v)*T(v)-10000;

needs to be

C(1,v)*m(1,v)*T(v) + C(2,v)*m(2)*T(v) + C(3,v)*m(3,v)*T(v)-10000;

In MATLAB, indexing a 2D array with a single index does not extract a row: instead it extracts a single element in a process known as "linear indexing".
