eigendecompose_sym() [1/2]

template<typename EigMat , require_eigen_t< EigMat > * = nullptr, require_not_st_var< EigMat > * = nullptr>

std::tuple< Eigen::Matrix< value_type_t< EigMat >, -1, -1 >, Eigen::Matrix< value_type_t< EigMat >, -1, 1 > > stan::math::eigendecompose_sym

(

const EigMat &

m

)

Return the eigendecomposition of the specified symmetric matrix.

Template Parameters

EigMat

type of the matrix

Parameters

m	Specified matrix.

Returns

A tuple V,D where V is a matrix where the columns are the eigenvectors of m, and D is a column vector of the eigenvalues of m. The eigenvalues are in ascending order of magnitude, with the eigenvectors provided in the same order.
