+/*  Purpose */
+/*  ======= */
+
+/*  SSTEVD computes all eigenvalues and, optionally, eigenvectors of a */
+/*  real symmetric tridiagonal matrix. If eigenvectors are desired, it */
+/*  uses a divide and conquer algorithm. */
+
+/*  The divide and conquer algorithm makes very mild assumptions about */
+/*  floating point arithmetic. It will work on machines with a guard */
+/*  digit in add/subtract, or on those binary machines without guard */
+/*  digits which subtract like the Cray X-MP, Cray Y-MP, Cray C-90, or */
+/*  Cray-2. It could conceivably fail on hexadecimal or decimal machines */
+/*  without guard digits, but we know of none. */
+
+/*  Arguments */
