How do I put it in?

x1 = [-4.2 -2.6 -1 0.6 2.2 3.8 5.4 7 8.6]
x2 = [0.8 2.4 4 5.6 7.2 8.8 10.4 12 13.6]

function Y = objectivefunction (X)
x1
x2
a = 1;
b = 5.1/(4*pi^2);
c = 5/pi;
r = 6;
s = 10;
t = 1/(8*pi);
Y = a*(x2 - b*x1^2 + c*x1 - r)^2 + s*(1-t)*cos(x1) + s
end

[-4.2 0.8], [-4.2 2.4],[-4.2 4],[-4.2 5.6],[-4.2 7.2],[-4.2 8.8],[-4.2 10.4],[-4.2 12],[-4.2 13.6]

[-2.6 0.8],[-2.6 2.4],[-2.6 4],[-2.6 5.6] , ...

I want to put all the x2 values in one x1 value sequentially.

Please let me know! Thank you!

x1 = [-4.2 -2.6 -1 0.6 2.2 3.8 5.4 7 8.6];
x2 = [0.8 2.4 4 5.6 7.2 8.8 10.4 12 13.6];
[X1, X2] = meshgrid(x1, x2);
pairs = [X1(:), X2(:)];

pairs(1:12,:)

ans = 12×2
