Detailed Description

template<typename Filtration_type, typename Coefficient_field>
class Gudhi::Persistence_interval_common< Filtration_type, Coefficient_field >

This is a class to store persistence intervals. Its main purpose is to exchange data in between different packages and provide unified way of writing a collection of persistence intervals to file.

Examples

rips_correlation_matrix_persistence.cpp.

Constructor & Destructor Documentation

Persistence_interval_common() [1/3]

template<typename Filtration_type , typename Coefficient_field >

Gudhi::Persistence_interval_common< Filtration_type, Coefficient_field >::Persistence_interval_common ( Filtration_type  birth, Filtration_type  death  )

inline

Constructor taking as an input birth and death of the pair.

Persistence_interval_common() [2/3]

template<typename Filtration_type , typename Coefficient_field >

Gudhi::Persistence_interval_common< Filtration_type, Coefficient_field >::Persistence_interval_common ( Filtration_type  birth, Filtration_type  death, unsigned  dim  )

inline

Constructor taking as an input birth, death and dimension of the pair.

Persistence_interval_common() [3/3]

template<typename Filtration_type , typename Coefficient_field >

Gudhi::Persistence_interval_common< Filtration_type, Coefficient_field >::Persistence_interval_common ( Filtration_type  birth, Filtration_type  death, unsigned  dim, Coefficient_field  field  )

inline

Constructor taking as an input birth, death, dimension of the pair as well as the number p such that this interval is present over Z_p field.

Member Function Documentation

operator!=()

template<typename Filtration_type , typename Coefficient_field >

bool Gudhi::Persistence_interval_common< Filtration_type, Coefficient_field >::operator!= ( const Persistence_interval_common< Filtration_type, Coefficient_field > &  i2 ) const

inline

Check if two persistence paris are not equal.

operator<()

template<typename Filtration_type , typename Coefficient_field >

bool Gudhi::Persistence_interval_common< Filtration_type, Coefficient_field >::operator< ( const Persistence_interval_common< Filtration_type, Coefficient_field > &  i2 ) const

inline

Operator to compare objects of a type Persistence_interval_common. One intervals is smaller than the other if it has lower persistence. Note that this operator do not take Arith_element into account when doing comparisons.

operator==()

template<typename Filtration_type , typename Coefficient_field >

bool Gudhi::Persistence_interval_common< Filtration_type, Coefficient_field >::operator== ( const Persistence_interval_common< Filtration_type, Coefficient_field > &  i2 ) const

inline

Operator to compare two persistence pairs. During the comparison all the fields: birth, death, dimensiona and arith_element_ are taken into account and they all have to be equal for two pairs to be equal.
