<p>Sparse matrix container This class acts as a generic row-wise container for sparse matrices. </p>
<p>It is designed to provide various methods to access the entries of the matrix. In particular, it does not meet the black box archetype; see <a class="el" href="class_lin_box_1_1_sparse_matrix.html">SparseMatrix</a> for an appropriate sparse matrix black box.</p>
