Detailed Description

template<class T>
class lti::dynamicMatrix< T >

This template class allows the use of matrices which change its dimensions without losing any data.

They are base on the STL-maps. The intention of this class is to provide a base data-structure for the generation of classification statistics (confusion-matrices). This is a VERY SLOW class, but highly confortable for dynamically growing matrices.
