cov_matrix_constrain() [3/6]

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

auto stan::math::cov_matrix_constrain ( const T &  x, Eigen::Index  K  )

inline

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).

This overload handles looping over the elements of a standard vector.

Template Parameters

T	A standard vector with inner type inheriting from Eigen::DenseBase or a var_value with inner type inheriting from Eigen::DenseBase with compile time dynamic rows and 1 column

Parameters

x	The vector to convert to a covariance matrix
K	The dimensions of the resulting covariance matrix

Exceptions

std::domain_error

if (x.size() != K + (K choose 2)).
