Detailed Description

template<class T, bool triangular = false>
class Faunus::PairMatrix< T, triangular >

Container for data between pairs.

Symmetric, dynamic NxN matrix for storing data about pairs. Set values with set(). If triangular==true the memory usage is reduced but introduces an if-statement upon access.

int i=2,j=3; // particle type, for example
PairMatrix<double> m;
m.set(i,j,12.0);
cout << m(i,j);         // -> 12.0
cout << m(i,j)==m(j,i); // -> true

Note

Vector of vector does not allocate contiguous memory
