AbstractWe construct a set of 71 weighing matrices, which contains all inequivalent matrices of order 13 and weight 9, by using the intersection pattern conditions with the aid of a computer. We provide a complete classification for weighing matrices of order 13 and weight 9 by showing that there are exactly eight inequivalent classes
