template<Eigen::UpLoType TriView, typename T1 , typename T2 , require_all_eigen_t< T1, T2 > * = nullptr, require_all_not_eigen_vt< is_var, T1, T2 > * = nullptr>

auto stan::math::mdivide_left_tri ( const T1 &  A, const T2 &  B  )

inline

Returns the solution of the system Ax=b when A is triangular.

Returns the solution of the system Ax=B when A is triangular.

Template Parameters

TriView	Specifies whether A is upper (Eigen::Upper) or lower triangular (Eigen::Lower).
T1	type of the triangular matrix
T2	type of the right-hand side matrix or vector

Parameters

A	Triangular matrix.
b	Right hand side matrix or vector.

Returns

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

Exceptions

std::domain_error

if A is not square or the rows of b don't match the size of A.

This overload handles arguments where one of T1 or T2 are var_value<T> where T is an Eigen type. The other type can also be a var_value or it can be a matrix type that inherits from EigenBase

Template Parameters

TriView	Specifies whether A is upper (Eigen::Upper) or lower triangular (Eigen::Lower).
T1	type of the triangular matrix
T2	type of the right-hand side matrix or vector

Parameters

A	Triangular matrix.
B	Right hand side matrix or vector.

Returns

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

Exceptions

std::domain_error

if A is not square or B does not have as many rows as A has columns.
