Constructor & Destructor Documentation

PwlRapMusic() [1/2]

PwlRapMusic::PwlRapMusic

(

)

Default constructor creates an empty POWELL RAP MUSIC algorithm which still needs to be initialized.

Definition at line 58 of file pwlrapmusic.cpp.

PwlRapMusic() [2/2]

PwlRapMusic::PwlRapMusic	(	MNELIB::MNEForwardSolution &	p_pFwd,
		bool	p_bSparsed,
		int	p_iN = 2,
		double	p_dThr = 0.5
	)

Constructor which initializes the POWELL RAP MUSIC algorithm with the given model.

Parameters

[in]	p_Fwd	The model which contains the gain matrix and its corresponding grid matrix.
[in]	p_bSparsed	True when sparse matrices should be used.
[in]	p_iN	The number (default 2) of uncorrelated sources, which should be found. Starting with. the strongest.
[in]	p_dThr	The correlation threshold (default 0.5) at which the search for sources stops.

Note: Since they are virtual they have to be implemented to be called. Even so the base class RAP MUSIC implementation is called.

Parameters

[in]	data.
[in]	tmin.
[in]	tstep.

Returns
