h = rectangle (…)

  Draw a rectangular patch defined by pos and curv.

  The variable `pos(1:2)` defines the lower left-hand corner of the patch and `pos(3:4)` defines its width and height. By default, the value of pos is `[0, 0, 1, 1]`.

  The variable curv defines the curvature of the sides of the rectangle and may be a scalar or two-element vector with values between 0 and 1. A value of 0 represents no curvature of the side, whereas a value of 1 means that the side is entirely curved into the arc of a circle. If curv is a two-element vector, then the first element is the curvature along the x-axis of the patch and the second along y-axis.

  If curv is a scalar, it represents the curvature of the shorter of the two sides of the rectangle and the curvature of the other side is defined by

      min (pos(1:2)) / max (pos(1:2)) * curv

  Additional property/value pairs are passed to the underlying patch command.

  If the first argument hax is an axes handle, then plot into this axes, rather than the current axes returned by `gca`.

  The optional return value h is a graphics handle to the created rectangle object.
