Implementation of the Kronecker product for matrices
Kolja Brix and I implemented the Kronecker tensor product for dense and sparse matrices, see the attachement for a proposal. At the moment one calls the function by
Eigen::kroneckerProduct(A, B, AB);
where matrix AB will be the Kronecker tensor product of the dense or sparse matrices A and B. If either A or B is of sparse matrix type, then AB has to be a sparse matrix too.
We would like to provide our code, so that it potentially can be integrated into Eigen and be used by everybody.
Is there any chance to do so?
