By default, the ## value of @var{pos} is @code{[0, 0, 1, 1]}. ## ## The variable @var{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 @var{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 @var{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 ## ## @example ## min (pos (1:2)) / max (pos (1:2)) * curv ## @end example ## ## Other properties are passed to the underlying patch command.
