Computes the k lowest eigenvalues and the eigenvectors of a real symmetric or complex Hermitian generalized definite eigenproblem, of the form A*x=(lambda)*B*x. B is also positive definite.

Parameters

[in,out]	a	(n, n)
[in,out]	b	(n, n)
[out]	e	(n)
[out]	v	(n, n)
[in]	preserve_mat	If true, the matrix a and b on exit are the same
[in,out]	bof	Bomb on failure.
