Computes all the eigenvalues and the eigenvectors of a real symmetric or complex Hermitian generalized definite eigenproblem, of the form \( Ax=\lambda Bx \). B is also positive definite.

For optimal performances, this uses the divide and conquer algoritm

Parameters

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