MechSys: Eigen{values,vectors} of 2nd O. Tensors

int Tensors::JacobiRot	(	Tensor2 const &	T,
		REAL	V0[3],
		REAL	V1[3],
		REAL	V2[3],
		REAL	L[3]
	)			`[inline]`

Jacobi Transformation of a Symmetric Matrix (given as a Tensor2) Out: Eigenvalues (array with 3 values).

$V0 = \begin{Bmatrix} Q(0,0) \\ Q(1,0) \\ Q(2,0) \end{Bmatrix}\qquad V1 = \begin{Bmatrix} Q(0,1) \\ Q(1,1) \\ Q(2,1) \end{Bmatrix}\qquad V2 = \begin{Bmatrix} Q(0,2) \\ Q(1,2) \\ Q(2,2) \end{Bmatrix}$

Returns:: the number of iterations

Parameters:

T	In: Tensor2 (Mandel) corresponding to a the matrix (A) we seek for the eigenvalues (SYMMETRIC and square)
V0	Out: Eigenvector (array with 3 values)
V1	Out: Eigenvector (array with 3 values)
V2	Out: Eigenvector (array with 3 values)
