hello, I am not sure if this is intended, but it appears that there is
redundant copy in
matrix.hpp

139         // Resizing
 140         BOOST_UBLAS_INLINE
 141         void resize (size_type size1, size_type size2, bool preserve =
true) {
 142             if (preserve) {
 143                 self_type temporary (size1, size2);
 144                 detail::matrix_resize_preserve<layout_type> (*this,
temporary);
 145             }
 146             else {
 147                 data ().resize (layout_type::storage_size (size1,
size2));
 148                 size1_ = size1;
 149                 size2_ = size2;
 150             }
 151         }

should line 147 read

 data ().resize (layout_type::storage_size (size1, size2), false);

thank you
