Destructor.

Member Function Documentation

◆ calculateSusceptibility() [1/2]

std::complex<double> TBTK::MatsubaraSusceptibilityCalculator::calculateSusceptibility ( const std::vector< double > &  k,
const std::vector< int > &  orbitalIndices,
std::complex< double >  energy 
)
virtual

Calculate the susceptibility.

Implements TBTK::SusceptibilityCalculator.

◆ calculateSusceptibility() [2/2]

std::vector<std::complex<double> > TBTK::MatsubaraSusceptibilityCalculator::calculateSusceptibility ( const DualIndex &  kDual,
const std::vector< int > &  orbitalIndices 
)
virtual

Calculate the susceptibility.

Implements TBTK::SusceptibilityCalculator.

◆ createSlave()

MatsubaraSusceptibilityCalculator* TBTK::MatsubaraSusceptibilityCalculator::createSlave ( )
virtual

Create slave SusceptibilityCalcuator. The slave reuses internal lookup tables used to speed up the calculations and should not be used after the generating master have been destructed.

Implements TBTK::SusceptibilityCalculator.

◆ setNumSummationEnergies()

void TBTK::MatsubaraSusceptibilityCalculator::setNumSummationEnergies ( unsigned int  numSummationEnergies)
inline

Set the number of summation energies.
