How do I use LHS(Latin Hypercube Sampling)?

x1=[-5,10]

x2=[0,15]

Branin function= @(x) (x(:,2)-5.1*x(:,1).^2./(4*pi^2)+5*x(:,1)./pi-6).^2 + 10*(1-1/(8*pi))*cos(x(:,1))+10;

n=30

d=2

X = lhsdesign(n,d);

I'd like to get the values from the boundary and objective functions.

Please let me know.

You could try with:

lb = [-5 0];
ub = [10, 15];
x = bsxfun(@plus, lb, bsxfun(@times, X, (ub-lb)); %new sample distribution
z = myfunction(x); % values of the objective function
