详细描述

template<enum Backend, class Matrix>
struct shogun::linalg::implementation::colwise_sum< Backend, Matrix >

Generic class colwise_sum which provides a static compute method. This class is specialized for different types of matrices and backend, providing a means to deal with various matrices directly without having to convert.
