I have an objective function : y = error_RT(Tx,Ty,theta,T1,T2) .The Tx,Ty,theta are the parameters to be solved , while the T1&T2 are constants calculated by other programs. The GA needs a @fun(x), but I don't know how to pass the constants I know to the program.
Code:
x = ga(y,3,[],[],[],[],[0,-2,-2],[pi,2,2]);
function y = error_RT(Tx,Ty,theta,T1,T2)
T = [Tx;Ty];
R = [cos(theta),sin(theta);-sin(theta),cos(theta)];
[m,~] = size(T1);
[n,] = size(T2);
for i = 1:m
T1(i,n)=(R*T1(i,n)'+T')';
end
Test1 = zeros(600,600);
Test2 = zeros(600,600);
for i = 1:m
Test1(round(T1(i,1)*100),round(T1(i,2)*100)) = Test1(round(T1(i,1)*100),round(T1(i,2)*100)) + 1;
end
for i = 1:n
Test2(round(T2(i,1)*100),round(T2(i,2)*100)) = Test2(round(T2(i,1)*100),round(T2(i,2)*100)) + 1;
end
y = sum(sum((Test1-Test2).^2));
end

Have a read here:
In your case it should look somehow like this:
x = ga(@(vars)error_RT(vars,T1,T2) ,3,[],[],[],[],[0,-2,-2],[pi,2,2]);
function y = error_RT(vars,T1,T2)
Tx = vars(1);
Ty = vars(2);
theta = vars(3);
... % your function code
... % your function code
... % your function code
end
