Detailed Description

template<typename T>
class fiber_bundle::antisymmetric_matrix_2x2< T >

Antisymmetric matrix with 2 rows and 2 columns.

Class antisymmetric_matrix_2x2 is a special kind of matrix class intended to be used in conjunction with various row_dofs_type classes (pod types). The pod types will be converted (cast) to appropriate matrix types. So, this class is also required to be a pod type also (ie: really just a struct with no inheritance, no constructors, no virtual functions, etc.).
