cholesky_factor_free() [1/2]

template<typename T , require_eigen_t< T > * = nullptr>

Eigen::Matrix< value_type_t< T >, Eigen::Dynamic, 1 > stan::math::cholesky_factor_free

(

const T &

y

)

Return the unconstrained vector of parameters corresponding to the specified Cholesky factor.

A Cholesky factor must be lower triangular and have positive diagonal elements.

Template Parameters

T	type of the Cholesky factor (must be derived from Eigen::MatrixBase)

Parameters

y	Cholesky factor.

Returns

Unconstrained parameters for Cholesky factor.

Exceptions

std::domain_error

If the matrix is not a Cholesky factor.
