+/*  Purpose */
+/*  ======= */
+
+/*  Using the divide and conquer method, CLAED0 computes all eigenvalues */
+/*  of a symmetric tridiagonal matrix which is one diagonal block of */
+/*  those from reducing a dense or band Hermitian matrix and */
+/*  corresponding eigenvectors of the dense or band matrix. */
+
+/*  Arguments */
+/*  ========= */
+
+/*  QSIZ   (input) INTEGER */
+/*         The dimension of the unitary matrix used to reduce */
+/*         the full matrix to tridiagonal form.  QSIZ >= N if ICOMPQ = 1. */
+
+/*  N      (input) INTEGER */
+/*         The dimension of the symmetric tridiagonal matrix.  N >= 0. */

+/*         On entry, the diagonal elements of the tridiagonal matrix. */
+/*         On exit, the eigenvalues in ascending order. */
+
+/*  E      (input/output) REAL array, dimension (N-1) */
+/*         On entry, the off-diagonal elements of the tridiagonal matrix. */
+/*         On exit, E has been destroyed. */
+
+/*  Q      (input/output) COMPLEX array, dimension (LDQ,N) */
+/*         On entry, Q must contain an QSIZ x N matrix whose columns */
+/*         unitarily orthonormal. It is a part of the unitary matrix */
+/*         that reduces the full dense Hermitian matrix to a */
+/*         (reducible) symmetric tridiagonal matrix. */

+
+/*  QSTORE (workspace) COMPLEX array, dimension (LDQS, N) */
+/*         Used to store parts of */
+/*         the eigenvector matrix when the updating matrix multiplies */
+/*         take place. */
+
+/*  LDQS   (input) INTEGER */
+/*         The leading dimension of the array QSTORE. */
+/*         LDQS >= max(1,N). */
