 <dd><p>EXPERIMENTAL: The index data for a CSR sparse matrix. </p>
 <p>A CSR sparse index manages the location of its non-zero values by two vectors.</p>
 <p>The first vector, called indptr, represents the range of the rows; the i-th row spans from indptr[i] to indptr[i+1] in the corresponding value vector. So the length of an indptr vector is the number of rows + 1.</p>
 <p>The other vector, called indices, represents the column indices of the corresponding non-zero values. So the length of an indices vector is same as the number of non-zero-values. </p>
