PlainPermutationType | operator* (const Transpose< PermutationBase< Other > > &other, const PermutationBase &perm) |
Class to view a vector of integers as a permutation matrix.
_IndicesType | the type of the vector of integer (can be any compatible expression) |
This class allows to view any vector expression of integers as a permutation matrix.
PermutationWrapper< _IndicesType > & applyTranspositionOnTheLeft | ( | Index | i, |
Index | j | ||
) | [inline, inherited] |
Multiplies *this by the transposition on the left.
PermutationWrapper< _IndicesType > & applyTranspositionOnTheRight | ( | Index | i, |
Index | j | ||
) | [inline, inherited] |
Multiplies *this by the transposition on the right.
This is a fast operation, it only consists in swapping two indices.
