Sorry, forgot to post my intended usage. I wanted to use std::transform over the rows. Consider something like this and couldn't do to the dereference of the row_iterator gives a double type. Are there any other ways to do this pattern in ublas?
struct vector_sum
{
template<class VectorType>
double operator()(const VectorType& vec)
{
return std::accumulate(vec.begin(), vec.end(), 0.0);
}
};
ublas::matrix<double> A(2.2);
ublas::vector<double> sums(2);
//Sum over rows.
std::transform(A.begin1(), A.end1(), sums.begin(), vector_sum());
