Detailed Description
This file implements several operations that operate element-wise on individual or pairs of containers.
Containers here means any of: mrpt::math::CVectorTemplace, mrpt::math::CArray, mrpt::math::CMatrixFixedNumeric, mrpt::math::CMatrixTemplate.
In general, any container having a type "mrpt_autotype" self-referencing to the type itself, and a dummy struct mrpt_container<> which is only used as a way to force the compiler to assure that BOTH containers are valid ones in binary operators. This restrictions have been designed as a way to provide "polymorphism" at a template level, so the "+,-,..." operators do not generate ambiguities for ANY type, and limiting them to MRPT containers.
In some cases, the containers provide specializations of some operations, for increased performance.
