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.
