◆ cholesky_factor_constrain() [4/5]

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

var_value< Eigen::MatrixXd > stan::math::cholesky_factor_constrain	(	const T &	x,
		int	M,
		int	N
	)

Return the Cholesky factor of the specified size read from the specified vector.

A total of (N choose 2) + N + (M - N) * N elements are required to read an M by N Cholesky factor.

Template Parameters

T	type of input vector (must be a `var_value<S>` where `S` inherits from EigenBase)

Parameters

x	Vector of unconstrained values
M	number of rows
N	number of columns
