		size_t	n_antennas,
		size_t	solution_interval

◆ GetNrSubSteps()

size_t dp3::ddecal::SolutionResampler::GetNrSubSteps ( ) const

inline

Get the number of substeps per solution interval.

NOTE: the current implementation for computing the number of substeps assumes that the solution interval is an integer multiple of the values in the number of solutions per direction.

◆ MapResampledToOriginal()

std::pair<size_t, size_t> dp3::ddecal::SolutionResampler::MapResampledToOriginal	(	size_t	time_index,
		size_t	antenna_index,
		size_t	direction_index,
		size_t	pol_index,
		size_t	n_pol
	)		const

Map index in upsampled solutions vector to the matching index in the original solution vector.

◆ Upsample() [1/2]

std::vector<std::vector<std::vector<ConstraintResult> > > dp3::ddecal::SolutionResampler::Upsample ( const std::vector< std::vector< std::vector< ConstraintResult >>> & solutions ) const

◆ Upsample() [2/2]

std::vector<std::vector<std::vector<std::complex<double> > > > dp3::ddecal::SolutionResampler::Upsample	(	const std::vector< std::vector< std::vector< std::complex< double >>>> &	solutions,
		size_t	n_pol
	)		const

Compute the upsampled solutions for dd interval solutions.

Dimension of returned vector is [n_times * n_substeps, n_channel_blocks, n_antenna * n_directions * n_pol].
