◆ mbs_schur_0()

int mbs_schur_0	(	double **	A,
		int	n,
		double **	T,
		double **	Z,
		double *	WR,
		double *	WI,
		int	reorder
	)

Compute the Schur decomposition.

Parameters

	A	Matrix for the Eigenvalue problem in row major
[in]	n	Size of the matrix
[out]	WR	Result of the Eigenvalue problem: real part of the n eigen values (ordered as they appear on the diagonal of the output Schur form T [n x 1]
[out]	WI	Result of the Eigenvalue problem: real part of the n eigen values (ordered as they appear on the diagonal of the output Schur form T [n x 1]
[out]	T	Schur decomposition matrix (re-ordered).
[out]	Z	Orthogonal matrix Z of Schur vectors [n X n] (re-ordered).
[in]	reorder	Flag for re-ordering: 1: re-ordered 0: non-ordered

Returns: 0 for successful exit.
