Draw 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)) * curvOther properties are passed to the underlying patch command.
The optional return value h is a graphics handle to the created rectangle object.
