Detailed Description

template<class T>
class mrpt::math::CMatrixTemplateObjects< T >

This template class extends the class "CMatrixTemplate" for storing "objects" at each matrix entry.

This class allows a very efficient representation of sparse matrixes where each cell is an arbitrary C++ class, but its use must carefully observe the following rules:

The type in the template especialization MUST be a class with a proper default constructor.
Initially all entries are set to nullptr.
Pointers can be manually asigned, or automatically created through a call to "CMatrixTemplateObjects<T>::allocAllObjects"
Independently of how pointers are asigned, memory will be free by destroying objects for each non-NULL entry in the matrix. In some special situations, the user can indicate not to free those objects by calling "CMatrixTemplateObjects<T>::setDestroyBehavior", then it is up to the user to free the memory. In all cases the default behavior is to free the memory.
Asignament operator with matrixes will COPY THE POINTERS, thus a copy of objects is not performed.
WARNING: Objects are not deleted while shrinking the matrix by calling "setSize", thus please call ""CMatrixTemplateObjects<T>::freeAllObjects" or manually delete objects before shrinking.
