<P>The routines below convert modulo-2 matrices between the form used by
the <A HREF="mod2dense.html">routines for dense modulo-2 matrices</A>
and the form used by the <A HREF="mod2dense.html">routines for sparse
modulo-2 matrices</A>.

<TT>mod2sparse.h mod2dense.h mod2convert.h</TT>
<P><A NAME="sparse_to_dense"><HR><B>mod2sparse_to_dense</B>:
Convert a modulo-2 matrix from sparse to dense form.</A>
<BLOCKQUOTE><PRE>
void mod2sparse_to_dense
( mod2sparse *m, /* Sparse matrix to convert */
mod2dense *r /* Place to store result */
)
</PRE></BLOCKQUOTE>
The dense matrix, r, must already have been allocated, and must have at
least as many rows and columns as m, the sparse matrix to be converted.
