First, I’ve wrote some source code,<\/p>\n

To fix this, I need to include “boost\/numeric\/ublas\/vector_proxy.hpp” like<\/p>\n

#include <boost\/numeric\/ublas\/matrix.hpp>
\n#include <boost\/numeric\/ublas\/triangular.hpp>
\n#include <boost\/numeric\/ublas\/vector.hpp>
\n#include <boost\/numeric\/ublas\/vector_proxy.hpp>
\n#include <boost\/numeric\/ublas\/lu.hpp>
\n#include <boost\/numeric\/ublas\/io.hpp><\/p><\/blockquote>\n
