void sparse_cached(const std::vector< Eigen::Triplet< Scalar > > &triplets, const Eigen::VectorXi &data, Eigen::SparseMatrix< Scalar > &X)
Build a sparse matrix from cached list of data and values.
void sparse_cached_precompute(const Eigen::MatrixBase< DerivedI > &I, const Eigen::MatrixBase< DerivedI > &J, Eigen::VectorXi &data, Eigen::SparseMatrix< Scalar > &X)
Build a sparse matrix from list of indices and values (I,J,V), similarly to the sparse function in ma...
