+/*  Purpose */
+/*  ======= */
+
+/*  DSPGVD computes all the eigenvalues, and optionally, the eigenvectors */
+/*  of a real generalized symmetric-definite eigenproblem, of the form */
+/*  A*x=(lambda)*B*x,  A*Bx=(lambda)*x,  or B*A*x=(lambda)*x.  Here A and */
+/*  B are assumed to be symmetric, stored in packed format, and B is also */
+/*  positive definite. */
+/*  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 */
+/*  ========= */
