                  <li>The number 0 indicates to use fast recursive factorization based on rank-1 updates from LUMOD package. </li>
                        
                  <li>The number 1 indicates to use LU factorization based on DGESV routine of LAPACK. </li>
                        
                  <li>The number 2 indicates to us
