Reply to comment by onkus in Can someone explain me the math behind this paper and tell me whether the way I have understood this paper is right or not? by eternal-abyss-77

I am asking what is

I - H is?

I get the same H as you say, but what is the matrix we get after I - H? Is it a mirror of H? As in paper, they said

I  -I
-I  I

So, the I in I-H is, normal identity matrix where major diagonal elements are 1 or is it mirror of H

What do you mean by “mirror of H"? I is always the identity matrix here. Why do you think it could be the "mirror" of H?

So I - HL will be

[ 1 0 0 0 0 -1 0 ]
[ 0 1 0 0 0 0 -1 ]
[ 0 0 1 0 0 0 0 ]
[ 0 0 0 1 0 0 0 ]
[ 0 0 0 0 1 0 0 ]
[ -1 0 0 0 0 1 0 ]
[ 0 -1 0 0 0 0 1 ]

This. And same goes for I - VL

Fine.

What do they mean by those rotations?
