Eigen::Matrix< return_type_t< 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 in the LDLT_factor
EigMat	type of the right hand side

Parameters

A	LDLT_factor
b	Right hand side matrix or vector.

Returns

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

Exceptions

std::domain_error

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