Detailed Description

for each diagonal, after we remove all the 1st stage var Aug fullMat = H | A' | = r_p (1) A | 0 | r_d =

x1 | x2 | xp | y1 | y2 | yp

H1 | | H1p | A1' | | p_1 | H2 | H2p | | A2' | p_2 Hp1 | Hp2 | Hp | A1p' | A2p' | Ap' = p_p (1) A1 | | A1p | | | d_1 | A2 | A2p | | | d_2 | | Ap | | | d_p

Reorder it

x1 | y1 | x2 | y2 | xp | yp

H1 | A1' | | | H1p | p11 A1 | | | | A1p | d_1 | | H2 | A2' | H2p | = p_2 (1) | | A2 | | A2p | d_2 H1p' | A1p' | H2p' | A2p' | Hp | Ap' p_p | | | | Ap | d_p

can do SC on [ Hp | Ap' ] [ Ap | ]
