MATLAB: Random Distribution Points inside rectangle

distribution point

hi every one how can i distribute randomly a number of points inside rectangle and every point has x,y ex: px(1)=100; py(1)=-100; and so forth where the rectangle code as shown bellow:-
x=-1100;
y=-1100;
rectangle('position',[x,y,2200,2200],'LineWidth',2,'LineStyle','--');

Best Answer

Try this:
numPoints = 1000;
width = 2200;
x = -1100
y = -1100;
rectangle('Position', [x, y, width, width],'LineWidth',2,'LineStyle','--');
grid on;
xRandom = width * rand(1, numPoints) - width / 2;
yRandom = width * rand(1, numPoints) - width / 2;
hold on;
plot(xRandom, yRandom, 'r.', 'MarkerSize', 10);
title('Random Points Inside a Rectangle', 'FontSize', fontSize, 'Interpreter', 'None');
xlabel('X', 'FontSize', fontSize);
ylabel('Y', 'FontSize', fontSize);
axis equal;
% Put axis at origin
ax = gca;
ax.XAxisLocation = 'origin';
ax.YAxisLocation = 'origin';
% Set up figure properties:
% Enlarge figure to full screen.
set(gcf, 'Units', 'Normalized', 'OuterPosition', [0 0 1 1]);
% Get rid of tool bar and pulldown menus that are along top of figure.
set(gcf, 'Toolbar', 'none', 'Menu', 'none');
% Give a name to the title bar.
set(gcf, 'Name', 'Demo by ImageAnalyst', 'NumberTitle', 'Off')
