template<unsigned int n>
constexpr unsigned int	MuonR4::vecIdxFromSymMat (unsigned int i, unsigned k)
	If a n-dimensional Matrix is symmetric, it has n* (n+1) /2 parameters The following function returns the global index when filling the content of the matrix into a vector via for (i = 0; i < n; ++i) { for (k =i; k<n; ++k){ } }. More...
template<int n>
constexpr std::array< unsigned, 2 >	MuonR4::symMatIdxFromVec (unsigned int k)
	Translates back the global index into the two matrix access indices under the assumption that the matrix is symmetric. More...
