The rectangle function.
width = 100; % whatever
height = 50; % whatever...
xCenter = 400; % Wherever...
yCenter = 800; % Wherever...
xLeft = xCenter - width/2;
yBottom = yCenter - height/2;
rectangle('Position', [xLeft, yBottom, width, height], 'EdgeColor', 'b', 'FaceColor', 'r', 'LineWidth', 4);
xlim([340, 460]);
ylim([740, 860]);
grid on;
