Detailed Description

template<class T>
class lti::hMatrix2D< T >

Homogeneous matrix to represent linear transformations in a two-dimensional projective space.

The two-dimensional transformations are represented by 3x3 matrices of the form:

where the terms represent a rotation and scaling and the terms the translation.
