Member Function Documentation

vine_swap()

template<class Master_matrix >

bool Gudhi::persistence_matrix::RU_vine_swap< Master_matrix >::vine_swap ( pos_index  index )

inline

Does a vine swap between two faces which are consecutives in the filtration. Roughly, if \( F \) is the current filtration represented by the matrix, the method modifies the matrix such that the new state corresponds to a valid state for the filtration \( F' \) equal to \( F \) but with the two faces at position position and position + 1 swapped. Of course, the two faces should not have a face/coface relation which each other ; \( F' \) has to be a valid filtration. See [21] for more information about vine and vineyards.

Parameters

position

PosIdx index of the first face to swap. The second one has to be at position + 1.

Returns

true If the barcode changed from the swap.

false Otherwise.

vine_swap_with_z_eq_1_case()

template<class Master_matrix >

bool Gudhi::persistence_matrix::RU_vine_swap< Master_matrix >::vine_swap_with_z_eq_1_case ( pos_index  index )

inline

Does the same than vine_swap, but assumes that the swap is non trivial and therefore skips a part of the case study.

Parameters

position

PosIdx index of the first face to swap. The second one has to be at position + 1.

Returns

true If the barcode changed from the swap.

false Otherwise.
