Functions

template<typename T , require_var_vector_t< T > * = nullptr>
var_value< Eigen::MatrixXd > stan::math::cov_matrix_constrain (const T &x, Eigen::Index K)
 Return the symmetric, positive-definite matrix of dimensions K by K resulting from transforming the specified finite vector of size K plus (K choose 2).
 
template<typename T , require_var_vector_t< T > * = nullptr>
var_value< Eigen::MatrixXd > stan::math::cov_matrix_constrain (const T &x, Eigen::Index K, scalar_type_t< T > &lp)
 Return the symmetric, positive-definite matrix of dimensions K by K resulting from transforming the specified finite vector of size K plus (K choose 2).
