+
+/*  Purpose */
+/*  ======= */
+
+/*  SSPEVD computes all the eigenvalues and, optionally, eigenvectors */
+/*  of a real symmetric matrix A in packed storage. 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 */
+/*  ========= */
+
+/*  JOBZ    (input) CHARACTER*1 */
+/*          = 'N':  Compute eigenvalues only; */

+/*          = 'U':  Upper triangle of A is stored; */

+/*          On entry, the upper or lower triangle of the symmetric matrix */
+/*          A, packed columnwise in a linear array.  The j-th column of A */
+/*          is stored in the array AP as follows: */
+/*          if UPLO = 'U', AP(i + (j-1)*j/2) = A(i,j) for 1<=i<=j; */
+/*          if UPLO = 'L', AP(i + (j-1)*(2*n-j)/2) = A(i,j) for j<=i<=n. */
