calculate_eigenvector()

void stan::math::opencl_kernels::calculate_eigenvector	(	const __global double_d *	l_plus,
		const __global double_d *	u_minus,
		const __global double *	subdiag,
		int	twist_idx,
		__global double *	eigenvectors
	)

Calculates an eigenvector from twisted factorization T - shift * I = L+.

• D+ * L+^T = U- * D- * U-^T.

  Parameters

  	l_plus	Subdiagonal of the L+.
  	u_minus	Superdiagonal of the U-.
  	subdiag	Subdiagonal of T
  	twist_idx	Twist index.
  [out]	eigenvectors	Matrix in which to store resulting vectors.
