for i=15:55 for j=2:9 plot (i,j) end end

for the above program, I want to display the coordinate of the point near the point in the figure. e.g. for the first point I want to display (15, 2) beside the point. How to do this?

Try this:

for i=15:55
  for j=2:9
    plot (i,j, 'b.', 'MarkerSize', 20)
  hold on;
    textString = sprintf('(%d, %d)', i, j);
    text(i-0.3, j+0.1, textString, 'FontSize', 7);
  end
end
grid on;
% Enlarge figure to full screen.
set(gcf, 'units','normalized','outerposition',[0 0 1 1]);
