~~Rename to BlockTwoLevelToeplitz~~
Constructor should not load any data, but can only receive a path to the defining vectors
The diagonalization process should not happen in the constructor but instead when befor the first projection/multiplication
getCols() and getRows() should be overloaded with routines not using the frequency domain
get rid of Kronecker-Products of Fourier-Matrices

World domination
Be able to extract parts of the matrix, w\o constructing it completely in the first place
speed-ups

The Fourier-Kronecker-Product-Problem should be mitigable by using the NDFourier.

Please be aware, that the _getCol() and _getRow() need to be overloaded in order to redefine the behaviour of getCols() and getRows().

What is meant by "should not load any data, but can only receive a path to the defining vectors"?

SebastianSemper commented 6 years ago

In view of recent developments, this issue is obsolete. Closing.
