Draw diagonals of rectangle

The code below

figure; hold on;
rectangle('Position',[1 2 5 6])
axis([0 10 0 10])
plot([1 6],[8 2],'k')
plot([1 6],[2 8],'k')

Draws a rectangle and I manually plotted 2 lines to conect the vertices of the rectangle, to draw the two diagonals of the rectangle.

Is there an easier or faster way to draw the diagonals of a rectangle, after you created it with the rectangle function?

If you're looking for a function, check out interconnections()

rectPos = [1 2 5 6]; %[left, bottom, width, height]; 
interconnections(repmat(cumsum(rectPos([1,3])),2,1), repmat(cumsum(rectPos([2,4])),2,1)', true); 
% This will also draw the rectangle

Alternatively,

rectPos = [1 2 5 6]; %[left, bottom, width, height]; 

rectangle('Position',rectPos); 
hold on
plot(cumsum(rectPos([1,3])), [cumsum(rectPos([2,4]));fliplr(cumsum(rectPos([2,4])))], '-k')
