Detailed Description

The RhoDMatrix class is designed to implement the storage of the rho and D matrices which are required for the spin correlation algorithm.

The matrix stores the spin as 2s+1.

Constructor & Destructor Documentation

ThePEG::RhoDMatrix::RhoDMatrix	(	PDT::Spin	inspin,
		bool	average = `true`
	)

inline

Standard constructor giving the spin as 2s+1.

The matrix starts out averaged, unless the second argument is false, when it is zeroed.

Definition at line 42 of file RhoDMatrix.h.

References _ispin, and _matrix.

PDT::Spin ThePEG::RhoDMatrix::iSpin ( ) const

inline

Get the spin.

The spin is returned as 2J+1 in units of hbar/2.
