Hi everybody,

I would like to know if there is a way to get a ublas matrix from a given
data pointer.

Here follows what I tried:

inline boost::numeric::ublas::matrix<double,
boost::numeric::ublas::column_major> cvToUblasMat( CvMat & m )
{
    using namespace boost::numeric::ublas;
    return matrix<double, column_major>( m.rows, m.cols,
shallow_array_adaptor<double>( m.rows * m.cols, m.data.db ) );
}

Thank you for helping...
