How would I go about finding the coordinates for random points inside this rectangle?
This is the code used:
n=20;
x=linspace(-1,1,n);
y=linspace(-1,1,n);
[x,y]=meshgrid(x,y);
z=zeros(n);
for i=1:n
for j=1:n
[N A] = acm_N([x(i,j) y(i,j)],[-1 -1; 1 -1; 1 1; -1 1],acm_def);
z(i,j)=N(10);
end
end
surf(x,y,z);
