First change the given pattern into a vector w of zeros and ones by turning each shaded square into a 1 and each unshaded square into a 0 and then lining up each column below the column before it. Then find a matrix M so that w'Mw=0 but u Mu #0 for all other nonzero vectors u of zeros and ones. a 0 0 0 W= 0 1 M= : va More Enter un
