XYZ_DISPLAY <br>
Display 3D Points in the MATLAB Graphics Window
</h1>
<hr>
<p>
<b>XYZ_DISPLAY</b>
is a MATLAB program which
reads the name of a data file
containing a list of 3D point coordinates, reads the data,
and displays the points in the MATLAB graphics window.
</p>
<p>
The file containing the point coordinates is in the <b>XYZ</b>
format.
</p>
<p>
The MATLAB command <b>scatter3</b>
is used to display the points.
</p>
<h3 align = "center">
Usage:
</h3>
<p>
<blockquote>
<b>xyz_display</b> ( <i>'filename.xyz'</i> )
</blockquote>
where
<ul>
<li>
<i>'filename.xyz'</i> is a file of XYZ point coordinate data.
</li>
</ul>
and displays a plot of the points.
