static void compute	(	const Matrix< 3, 3, P, B > &	m,
		Matrix< 3, 3, P > &	eig,
		Vector< 3, P > &	ev
	)		[static]

Compute an eigensystem.

Parameters:

m	Input matrix (assumed to be symmetric)
eig	Eigen vector output
ev	Eigen values output

Need A,B = cubert(alpha +- beta) Turn in to r, theta r^(1/3) * e^(i * theta/3)
