<dd><p>Return a handle <var>h</var> to a new progress indicator ("waitbar") object.
</p>
<p>The waitbar is filled to fraction <var>frac</var> which must be in the range
[0, 1].
</p>
<p>The optional message <var>msg</var> is centered and displayed above the waitbar.
</p>
<p>A cancel button can be added to the bottom of the waitbar using the
<code>"createcancelbtn"</code> property of waitbar figures. The action to be
executed when the user presses the button is specified using a string or
function handle <var>fcn</var>.
</p>
<p>The appearance of the waitbar figure window can be configured by passing
<var>prop</var>/<var>val</var> pairs to the function. The full list of properties is
documented at <a href="Figure-Properties.html">Figure Properties</a>.
</p>
<p>When called with a single input the current waitbar, if it exists, is
updated to the new value <var>frac</var>. If there are multiple outstanding
waitbars they can be updated individually by passing the handle <var>h</var>
of the specific waitbar to modify.
