Detailed Description

The concept SimplicialComplexForAlpha describes the requirements for a type to implement a simplicial complex, that can be created from a Alpha_complex.

Member Typedef Documentation

◆ Boundary_simplex_range

typedef unspecified Gudhi::alpha_complex::SimplicialComplexForAlpha::Boundary_simplex_range

Iterator over the boundaries of the complex, in an arbitrary order.

'value_type' must be 'Simplex_handle'.

◆ Filtration_value

typedef unspecified Gudhi::alpha_complex::SimplicialComplexForAlpha::Filtration_value

Handle to specify the simplex filtration value.

◆ Simplex_handle

typedef unspecified Gudhi::alpha_complex::SimplicialComplexForAlpha::Simplex_handle

Handle to specify a simplex.

◆ Simplex_vertex_range

typedef unspecified Gudhi::alpha_complex::SimplicialComplexForAlpha::Simplex_vertex_range

Iterator over vertices of a simplex.

'value type' must be 'Vertex_handle'.

◆ Skeleton_simplex_range

typedef unspecified Gudhi::alpha_complex::SimplicialComplexForAlpha::Skeleton_simplex_range

Iterator over the simplices of the skeleton of the complex, for a given dimension.

'value_type' must be 'Simplex_handle'.

◆ Vertex_handle

typedef unspecified Gudhi::alpha_complex::SimplicialComplexForAlpha::Vertex_handle

int Gudhi::alpha_complex::SimplicialComplexForAlpha::dimension ( Simplex_handle simplex )

Gets the 'simplex' dimension.

◆ make_filtration_non_decreasing()

void Gudhi::alpha_complex::SimplicialComplexForAlpha::make_filtration_non_decreasing ( )

Browses the simplicial complex to make the filtration non-decreasing.

◆ num_vertices()

std::size_t Gudhi::alpha_complex::SimplicialComplexForAlpha::num_vertices ( )

Returns the number of vertices in the simplicial complex.

◆ prune_above_filtration()

void Gudhi::alpha_complex::SimplicialComplexForAlpha::prune_above_filtration ( Filtration_value filtration )
