Hi

--1 has anybody some material that can help me to understand mdds
library ?(some example, some pdf ……)
Google if your friend, first hit on a search is:
http://kohei.us/2012/07/20/mdds-multi_type_vector-explained/

That blog post is a little outdated now.  For multi_type_vector, I've
written a more up-to-date one over here:

http://kohei.us/files/mdds/doc/multi_type_vector.html

The bug is about the performance of Calc's internal matrix class, which
uses mdds::multi_type_matrix.  I'm afraid the documentation on that is
still largely work-in-progress, and right now we only have just some
API references:

http://kohei.us/files/mdds/doc/multi_type_matrix.html

That said, internally multi_type_matrix is a very thin wrapper around
multi_type_vector, so much of what is discussed on multi_type_vector
still applies there.

I'm also interested in some feedback on what sort of documentation,
examples, tutorials would be useful to new users of mdds as well as the
seasoned ones.  I may not be able to get something written quickly, but
knowing the areas where improvement is needed most would be a good
first step.

Thanks,

Kohei
