Hi Oswin,
Thanks for your reply. I have seen the tutorial already. I am new to boost so I apologize in advance if my question is very basic. So shall I have to put the serialize part inside my Eigen::Matrix class to work ? or can I put it inside my class ? Can you give me a small example please or explain a bit ?

Regards,
Dip
