trace_quad_form() [3/3]

template<typename Mat1 , typename Mat2 , require_all_matrix_t< Mat1, Mat2 > * = nullptr, require_any_var_matrix_t< Mat1, Mat2 > * = nullptr>

var stan::math::trace_quad_form ( const Mat1 &  A, const Mat2 &  B  )

inline

Compute trace(B^T A B).

This overload handles arguments where one of Mat1 or Mat2 are var_value<T> where T is an Eigen type. The other type can also be a var_value or it can be a type that inherits from EigenBase

Template Parameters

Mat1	type of the first matrix
Mat2	type of the second matrix

Parameters

A	matrix
B	matrix

Returns

The trace of B^T A B

Exceptions

std::domain_error	if A is not square
std::domain_error	if A cannot be multiplied by B
