Hi,
I have used Eigen::Matrix class  in my project. Now i wants to serialize the value of it through Boost::Serialize. Can someone help me on how to achieve that. 

My class is following,
class RandomNode {
private:
friend class boost::serialization::access;
template<class Archive>
void serialize(Archive & ar, const unsigned int version)
{ ar & is_leaf_; ar & depth_; ar & num_classes_; ar & num_features_; // Split node members ar & random_feature_indices_; ar & random_feature_weights_; ar & threshold_; ar & leftChild_; ar & rightChild_; }
bool is_leaf_;
int depth_;
int num_classes_;
int num_features_; // Split node members
VectorXi random_feature_indices_;
VectorXd random_feature_weights_;
double threshold_;
RandomNode* leftChild_;
RandomNode* rightChild_; // Methods and so on
}

And i am getting the following error :


/usr/include/boost/serialization/access.hpp:118:9: error: ‘class Eigen::Matrix<double, 10000, 1>’ has no member named ‘serialize’

thanks in advance.

Regards,
Dip
