Components and Decomposition

• decompose(HepBoost & b, HepRotation & r) $\triangleright$ see eqn. 
• decompose(HepRotation & r, HepBoost & b) $\triangleright$ see eqn. 
• col1( ) col2( ) col3( ) col4( )
• row1( ) row2( ) row3( ) row4( )
• xx( ) xy( ) xz( ) xt( )
• yx( ) yy( ) yz( ) yt( )
• zx( ) zy( ) zz( ) zt( )
• tx( ) ty( ) tz( ) tt( )

• HepRep4x4 rep4x4( )

• ostream & operator$<<$( ostream & os, const Hep4RotationInterface & lt )

Also, components can be accessed by C-style and array-style subscripting:

• lt[i][j] $\triangleright$ see eqn. 
• lt(i,j) $\triangleright$ see eqn. 

The following are applicable to HepBoost but not to HepLorentzRotation:

• Hep3vector direction( ) beta( ) gamma( )
• Hep3Vector boostVector( )
• HepRep4x4Symmetric rep4x4Symmetric( )
