*** Simplex tree construction with Z/2Z coefficients on weighted graph Klein bottle file:
./Simplex_tree_example_from_cliques_of_graph ../../../data/points/Klein_bottle_complex.txt 2
Insert the 1-skeleton in the simplex tree in 0 s.
Expand the simplex tree in 0 s.
Information of the Simplex Tree:
Number of vertices = 10 Number of simplices = 82
with Z/3Z coefficients:
./Simplex_tree_example_from_cliques_of_graph ../../../data/points/Klein_bottle_complex.txt 3
Insert the 1-skeleton in the simplex tree in 0 s.
Expand the simplex tree in 0 s.
Information of the Simplex Tree:
Number of vertices = 10 Number of simplices = 106
*** Simplex_tree computed and displayed from a 3D alpha complex:
