Though this does work in generating equal separation, I'm looking for how I can get N number of coordinates (say 80 coordinates) all over a square (say 20 by 20), and if you were to join the coordinates with their neighbors, you would get an equilateral triangle.

n=10
distance=4;
x1=0:distance:(n-1)*distance;
x2=distance/2:distance:n*distance-distance/2;
distancev=distance*sin(pi/3);
y1=0:distancev*2:(n-1)*distancev;
y2=distancev:2*distancev:n*distancev;
a1=repmat(x1,n/2,1);
a2=repmat(y1',1,n);
b1=repmat(x2,n/2,1);
b2=repmat(y2',1,n);
x=[a1(:);b1(:)];
y=[a2(:);b2(:)]
scatter(x,y)
