Detailed Description

Lorentz transformation class with the (4D) transformation represented by a 4x4 orthosymplectic matrix.

See also Boost, BoostX, BoostY and BoostZ for classes representing specialized Lorentz transformations. Also, the 3-D rotation classes can be considered to be special Lorentz transformations which do not mix space and time components.
