Member Function Documentation

template<typename T> void atlas::setutils::Permutation::permute (  std::vector< T > &  v  )  const

Applies our permutation |pi| to the vector |v|. In other words, we send each entry v[i] to the new position v[pi[i]]; this means that afterwards for all |i|: |new_v[pi[i]]==old_v[i]|, or equivalently $new_v[i]=old_v[pi^{-1}[i]]$. Note that this is {not} the same notion of permutation of entries used in the methods above, nor in the |permute| methods of matrices and bitsets; with respect to those we use the inverse permutation We are able to perform this permutation essentially in-place, using an auxiliary vector<bool>.
