Function Documentation

int blEigen	(	REAL **	matrix,
		REAL **	eigenVectors,
		REAL *	eigenValues,
		int	matrixSize
	)

Parameters

[in]	**matrix	Symmetric matrix
[in]	matrixSize	Dimension of the matrix
[out]	**eigenVectors	The eigen vectors
[out]	*eigenValues	The eigen values

Returns

If >0, the number of Jacobi rotations performed If <0, error: EIGEN_NOMEMORY - memory allocation EIGEN_NOCONVERGE - didn't converge in 50 iterations

Calculates the eigenvalues and eigenvectors of a REAL symmetric matrix Note that this routine destroys the values above the diagonal of the matrix.
