template<typename T , typename EigMat , require_eigen_vt< std::is_arithmetic, T > * = nullptr, require_eigen_vt< is_fvar, EigMat > * = nullptr>

Eigen::Matrix< value_type_t< EigMat >, Eigen::Dynamic, EigMat::ColsAtCompileTime > stan::math::mdivide_left_ldlt ( LDLT_factor< T > &  A, const EigMat &  b  )

inline

Returns the solution of the system Ax=b given an LDLT_factor of A.

Template Parameters

T	type of matrix for the LDLT_factor
EigMat	type of the right-hand side matrix or vector

Parameters

A	LDLT_factor
b	right-hand side matrix or vector

Returns

x = b A^-1, solution of the linear system.

Exceptions

std::domain_error

if rows of b don't match the size of A.
