+
+/*  Purpose */
+/*  ======= */
+
+/*  DSTEGR computes selected eigenvalues and, optionally, eigenvectors */
+/*  of a real symmetric tridiagonal matrix T. Any such unreduced matrix has */
+/*  a well defined set of pairwise different real eigenvalues, the corresponding */
+/*  real eigenvectors are pairwise orthogonal. */
+
+/*  The spectrum may be computed either completely or partially by specifying */
+/*  either an interval (VL,VU] or a range of indices IL:IU for the desired */
+/*  eigenvalues. */
+
+/*  DSTEGR is a compatability wrapper around the improved DSTEMR routine. */
+/*  See DSTEMR for further details. */
+
+/*  One important change is that the ABSTOL parameter no longer provides any */
+/*  benefit and hence is no longer used. */
+
+/*  Note : DSTEGR and DSTEMR work only on machines which follow */
+/*  IEEE-754 floating-point standard in their handling of infinities and */
+/*  NaNs.  Normal execution may create these exceptiona values and hence */
+/*  may abort due to a floating point exception in environments which */
+/*  do not conform to the IEEE-754 standard. */
+
+/*  Arguments */
+/*  ========= */
+
+/*  JOBZ    (input) CHARACTER*1 */
+/*          = 'N':  Compute eigenvalues only; */

+/*  RANGE   (input) CHARACTER*1 */
+/*          = 'A': all eigenvalues will be found. */
+/*          = 'V': all eigenvalues in the half-open interval (VL,VU] */
+/*                 will be found. */
+/*          = 'I': the IL-th through IU-th eigenvalues will be found. */

+
+/*  E       (input/output) DOUBLE PRECISION array, dimension (N) */
+/*          On entry, the (N-1) subdiagonal elements of the tridiagonal */
+/*          matrix T in elements 1 to N-1 of E. E(N) need not be set on */

+/*          On exit, E is overwritten. */
+
+/*  VL      (input) DOUBLE PRECISION */

+/*          is split. ISUPPZ is only accessed when JOBZ is 'V' and N > 0. */
+
+/*  WORK    (workspace/output) DOUBLE PRECISION array, dimension (LWORK) */
