Detailed Description

template<int N>
struct tarch::la::VectorCompare< N >

Comparison operator for boolean vectors.

If you wanna store sets of vectors (e.g. in a map), the STL libraries are by default falling back to a bit-wise comparison. This might not be of use if you manage sets/maps of double vectors. In this case, you wanna the container take into account machine precision. In such a case, declare the map e.g. as follows:

std::map<tarch::la::Vector<DIMENSIONS,double> , int, tarch::la::VectorCompare<DIMENSIONS>  >  _vertex2IndexMap;
