[Boost-users] Compilation problems from a ublas newbie

From: Pete Masterson (mitchubus_at_[hidden])

Hi all,

I tried to compile the 2D point morph example from
http://elonen.iki.fi/code/tpsdemo/2d-morph.cpp and
http://elonen.iki.fi/code/tpsdemo/ludecomposition.h
with the latest Boost 1.33.1 but I come across two
errors. These seem to be related to the use of
iterators with ublas::matrix_row and
ublas::matrix_column. As a Boost newbie, the errors
are not at all intuitive to me, however. I assume that
the code above was generated for an older version of
Boost and fails to compile now.

I would be deeply grateful if you could consider
taking a look at the attached the compiler output in
the out.txt file.

I appreciate your help very much.

Regards,
Peter
