<dd><p>Draw a rectangular patch defined by <var>pos</var> and <var>curv</var>.
</p>
<p>The variable <code><var>pos</var>(1:2)</code> defines the lower left-hand corner of
the patch and <code><var>pos</var>(3:4)</code> defines its width and height. By
default, the value of <var>pos</var> is <code>[0, 0, 1, 1]</code>.
</p>
<p>The variable <var>curv</var> 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</var> 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.
</p>
<p>If <var>curv</var> 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
</p>
<div class="example">
<pre class="example">min (pos(1:2)) / max (pos(1:2)) * curv
</pre></div>
<p>Additional property/value pairs are passed to the underlying patch command.
</p>
<p>If the first argument <var>hax</var> is an axes handle, then plot into this axis,
rather than the current axes returned by <code>gca</code>.
</p>
<p>The optional return value <var>h</var> is a graphics handle to the created
rectangle object.
