Classes
class	chomp::homology::Simplex
	This class defines a simplex as a geometric cell that can be used as a member of a geometric complex. More...
Namespaces
namespace	chomp
	This namespace contains the entire CHomP library interface.
namespace	chomp::homology
	This namespace contains the core of the homology computation procedures and related classes and templates contained in the CHomP C++ library.
Typedefs
typedef Simplex	chomp::homology::simplex
	A lower-case name for a simplex [deprecated].
typedef gcomplex< simplex, integer >	chomp::homology::simplicialcomplex
	A lower-case name for a simplicial complex [deprecated].
typedef hashedset< simplex >	chomp::homology::simplices
	An alternative name for a set of simplices [deprecated].
Functions
int	chomp::homology::operator== (const Simplex &s, const Simplex &t)
	The operator == that compares whether the two simplices are the same, that is, have the same vertices in the same order.
int	chomp::homology::operator!= (const Simplex &s, const Simplex &t)
	The operator != verifies if the two simplices are different.
int	chomp::homology::boundarylength (const Simplex &s)
	Returns the length of the boundary of a simplex.
int	chomp::homology::boundarycoef (const Simplex &, int i)
	Returns the i-th coefficient in the boundary of a simplex.
Simplex	chomp::homology::boundarycell (const Simplex &s, int i)
	Returns the i-th boundary face of a simplex.
Simplex	chomp::homology::boundarycell (const Simplex &s, int i, bool)
	Returns the i-th boundary face of a simplex.
std::ostream &	chomp::homology::operator<< (std::ostream &out, const Simplex &s)
	Writes a simplex to the output stream in the text format.
std::istream &	chomp::homology::operator>> (std::istream &in, Simplex &s)
	Reads a simplex from an imput stream from a text format.

Detailed Description

This file contains the definition of a class which represents a simplex.

The definition complies with the requirements of the homology software so that simplices can be used as cells in a geometric complex, and also in algorithms for homology computation.
