How to plot a box on an existing plot?

I know it is possible to use the rectangle option but that requires you to specify [x y width height]. I want to plot a box with [xmin xmax ymin ymax] or similar as I don't know the width and height and only the coordinates.

xmin=0;
xmax=1;
ymin=0;
ymax=1;
plot([xmin xmax xmax xmin xmin],[ymin ymin ymax ymax ymin])

or

rectangle('position',[xmin ymin xmin xmax])

I think there is a typo. It should be:

rectangle('position',[xmin ymin xmax ymax])
