-*  Purpose
-*  =======
-*
-*  DSYGST reduces a real symmetric-definite generalized eigenproblem
-*  to standard form.
-*
-*  If ITYPE = 1, the problem is A*x = lambda*B*x,
-*  and A is overwritten by inv(U**T)*A*inv(U) or inv(L)*A*inv(L**T)
-*
-*  If ITYPE = 2 or 3, the problem is A*B*x = lambda*x or
-*  B*A*x = lambda*x, and A is overwritten by U*A*U**T or L**T*A*L.
-*
-*  B must have been previously factorized as U**T*U or L*L**T by DPOTRF.

-*          triangular part of the matrix A, and the strictly lower

-*          leading N-by-N lower triangular part of A contains the lower
-*          triangular part of the matrix A, and the strictly upper
-*          triangular part of A is not referenced.
