XYZL_DISPLAY <br>
Display 3D Points and Lines in the MATLAB Graphics Window
</h1>
<hr>
<p>
<b>XYZL_DISPLAY</b>
is a MATLAB program which
reads XYZL information
containing a list of 3D point coordinates, and the indices of points
that form lines, and displays a plot in the MATLAB graphics window.
</p>
<p>
The program SXYZ_DELAUNAY, which creates a Delaunay triangulation on
a sphere, is an example of a program whose output is in the form
that this program can display.
</p>
<h3 align = "center">
Usage:
</h3>
<p>
<blockquote>
<b>xyzl_display</b> ( <i>'prefix'</i> )
</blockquote>
where
<ul>
<li>
<i>'prefix'</i> is the common file prefix.
</li>
</ul>
reads the point coordinate data in <i>'prefix.xyz'</i> and
the line information in <i>'prefix.xyzl'</i>, and displays a plot.
