-*  Purpose
-*  =======
-*
-*  ZHPGST reduces a complex Hermitian-definite generalized
-*  eigenproblem to standard form, using packed storage.
-*
-*  If ITYPE = 1, the problem is A*x = lambda*B*x,
-*  and A is overwritten by inv(U**H)*A*inv(U) or inv(L)*A*inv(L**H)
-*
-*  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**H or L**H*A*L.
-*
-*  B must have been previously factorized as U**H*U or L*L**H by ZPPTRF.
