Description

This is structural abstraction (which is optional for a matrix but implemented for most we use) that allows to interrogate matrix operands whether they are dense or sparse, row or column-major or diagonal etc. without coding to a concrete matrix implementation class.

this allows to build structure-optimized iterations.
