MATLAB: Coordinates of a square array with a loop

distance between pointsloopssquare array

I have a 7×7 array of points, all equally spaced, 1 unit apart, hence the coordinate matrix looks something like:

d=[0,0; 0,1; 0,2; 0,3...; 1,0; 1,1; ...1,6; etc]

how to I generate this matrix for any N number of points in the array? (it's always going to be a square of m x m)

I assume you're looking for meshgrid, though your question isn't clear.

[xx yy] = meshgrid(0:6);
[xx(:) yy(:)]

The line function can be used to draw the lines between the dots.

for i = 0.25 : 0.25 : 0.75
    line([i i],[0 1],'LineStyle','-','Color','black') % To draw vertical lines
    line([0,1],[i i],'LineStyle','-','Color','black') % To draw horizontal lines
end
