cos(x1)+cos(x2)+cos(x3)+cos(x4)+cos(x5)=0.9;;
cos(5(x1))+cos(5(x2))+cos(5(x3))+cos(5(x4))+cos(5(x5))=0;;
cos(7(x1)))+cos(7(x2))+cos(7(x3))+cos(7(x4))+cos(7(x5))=0;;
cos(11(x1))+cos(11(x2))+cos(11(x3))+cos(11(x4))+cos(11(x5))=0;;
cos(13(x1))+cos(13(x2))+cos(13(x3))+cos(13(x4))+cos(13(x5))=0;;
0<x1<x2<x3<x4<x5<90degree;;
I have done some programming. But it has some error. I can not understand it.
function z = gener (x)
A=[1 5 7 11 13;1 5 7 11 13;1 5 7 11 13;1 5 7 11 13;1 5 7 11 13];
rhs=[0.9 0 0 0 0].';
z=sum( cos( A*diag(x(:) )) ,2) - rhs;
end
Please tell me how I will get output ?

I cannot see what you have dne and what you are trying to get. Please format your code with the {} Code button. And please check the documentation for how to write a fitness function.

Please show your code that calls ga, and please show the error message.
Also remember that cos() expects radians so use cosd() if you want degrees.
