+/*  Purpose */
+/*  ======= */
+
+/*  ZLALS0 applies back the multiplying factors of either the left or the */
+/*  right singular vector matrix of a diagonal matrix appended by a row */
+/*  to the right hand side matrix B in solving the least squares problem */
+/*  using the divide-and-conquer SVD approach. */
+
+/*  For the left singular vector matrix, three types of orthogonal */
+/*  matrices are involved: */
+
+/*  (1L) Givens rotations: the number of such rotations is GIVPTR; the */
+/*       pairs of columns/rows they were applied to are stored in GIVCOL; */
+/*       and the C- and S-values of these rotations are stored in GIVNUM. */
+
+/*  (2L) Permutation. The (NL+1)-st row of B is to be moved to the first */
+/*       row, and for J=2:N, PERM(J)-th row of B is to be moved to the */
+/*       J-th row. */
+
+/*  (3L) The left singular vector matrix of the remaining matrix. */
+
+/*  For the right singular vector matrix, four types of orthogonal */
+/*  matrices are involved: */
+
+/*  (1R) The right singular vector matrix of the remaining matrix. */
+
+/*  (2R) If SQRE = 1, one extra Givens rotation to generate the right */
+/*       null space. */
+
+/*  (3R) The inverse transformation of (2L). */
