Detailed Description

template<int tree_dim, int world_dim, class elem_t, class common_data_t>
struct ug::ntree_traits< tree_dim, world_dim, elem_t, common_data_t >

The following methods have to be provided for the given vector-type:

void VecSet(vector_t& vOut, real_t value); // sets all components of 'v' to 'value'.
void VecAdd(vector_t& vOut, const vector_t& v1, const vector_t& v2); // performs vOut = v1 + v2.
void VecScale(vector_t& vOut, const vector_t& v, real_t s); // performs vOut = s * v.
ug::VecSet
void VecSet(vector_t &vInOut, typename vector_t::value_type s)
Set each vector component to scalar (componentwise)
Definition math_vector_functions_common_impl.hpp:539
ug::VecAdd
void VecAdd(vector_t &vOut, const vector_t &v1, const vector_t &v2)
adds two MathVector<N>s and stores the result in a third one
Definition math_vector_functions_common_impl.hpp:185
ug::VecScale
void VecScale(vector_t &vOut, const vector_t &v, typename vector_t::value_type s)
scales a MathVector<N>
