Detailed Description

Stores a hierarchy of block matrices, such that each level matrix holds all matrices (or leaves) of that level of a given matrix.

Constructor & Destructor Documentation

TMatrixHierarchy	(	TMatrix *	A,
		const bool	with_blocked
	)

construct a hierarchy based on given matrix A

Parameters

A	matrix to construct hierarchy with
with_blocked	if true, also block matrices will be stored in hierarchy
