HB_TO_ST<br>
Harwell Boeing Sparse Matrix File <br>
converted to<br>
ST Sparse Triplet File
</h1>
<hr>
<p>
<b>HB_TO_ST</b>
is a MATLAB program which
accepts the name of
a file containing a sparse matrix in the
Harwell Boeing Sparse Matrix File Format, and which reads
that data and writes a corresponding Sparse Triplet (ST) file.
</p>
<h3 align = "center">
Usage:
</h3>
<p>
<blockquote>
<b>hb_to_st</b> ( <i>'hb_file'</i>, <i>'st_file'</i> )
</blockquote>
where
<ul>
<li>
<i>'hb_file'</i> is the name of the Harwell Boeing file to be read.
</li>
<li>
<i>'st_file'</i> is the name of the Sparse Triplet file to be created.
