trace_dot() [1/3]

template<typename EigMat1 , typename EigMat2 , require_all_eigen_t< EigMat1, EigMat2 > * = nullptr, require_any_vt_fvar< EigMat1, EigMat2 > * = nullptr>

return_type_t< EigMat1, EigMat2 > stan::math::trace_dot ( EigMat1 &&  A, EigMat2 &&  B  )

inline

Compute the trace of the product of two matrices with forward-mode autodiff support.

Template Parameters

EigMat1	A type either inheriting from Eigen::DenseBase or a var_value with an inner type inheriting from Eigen::DenseBase
EigMat2	A type either inheriting from Eigen::DenseBase or a var_value with an inner type inheriting from Eigen::DenseBase

Parameters

A	first matrix (m x n)
B	second matrix (n x m)

Returns

trace of A * B

Exceptions

std::invalid_argument

if A and B have incompatible dimensions
