Ai being 0,1 or 0,-1 matrix means that 1 and -1 can't be in the same Ai
Ai being 0,1 or 0,-1 matrix means that 1 and -1 can't be in the same Ai
Given a matrix
M = matrix(ZZ, [[1, 1, 1, 1], [1, -1, 1, -1], [1, 1, -1, -1], [1, -1, -1, 1]])
write
M = A1 + A2 + A3 + A4 + A5 + A6
where each Ai being is either a 0,1 or 0,-1 matrix. What are all such possible combinations of Ai's?
