Detailed Description

template<typename Lhs, typename Rhs>
class Eigen::KroneckerProduct< Lhs, Rhs >

Kronecker tensor product helper class for dense matrices.

This class is the return value of kroneckerProduct(MatrixBase, MatrixBase). Use the function rather than construct this class directly to avoid specifying template prarameters.

Template Parameters

Lhs	Type of the left-hand side, a matrix expression.
Rhs	Type of the rignt-hand side, a matrix expression.
