Reduces Hermitian-definite generalized eigenvalue problem to standard form.

Parameters

ibtype	Type of the problem (1, 2, 3).
aa	Matrix A.
desca	Descriptor of matrix A.
bb	Right hand side of the eigenvalue equation (B).
desb	Descriptor of matrix B.
scale	Scaling factors on return.
uplo	Upper or lower diagonal matrix (default: "L")
