Member Function Documentation

◆ NSolutionPolarizations()

size_t dp3::ddecal::ScalarSolver::NSolutionPolarizations ( ) const

inlineoverridevirtual

Returns: The number of polarizations in the solution.

Implements dp3::ddecal::SolverBase.

◆ Solve()

SolveResult dp3::ddecal::ScalarSolver::Solve	(	const FullSolveData &	data,
		std::vector< std::vector< DComplex >> &	solutions,
		double	time
	)

overridevirtual

Solves multi-directional Jones matrices. Takes the (single) measured data and the (multi-directional) model data, and solves the optimization problem that minimizes the norm of the differences.

Parameters

data	Buffer with weighted data and model data.
solutions	The per-channel and per-antenna solutions. solutions[ch] is a pointer for channelblock ch to antenna x directions x pol solutions.

Reimplemented from dp3::ddecal::SolverBase.

The documentation for this class was generated from the following file:
