In mathematics, a weighing matrix W of order n and weight w is an n × n (0,1,-1)-matrix such that WWᵀ=wIₙ, where Wᵀ is the transpose of W and Iₙ is the identity matrix of order n. For convenience, a weighing matrix of order n and weight w is often denoted by W(n,w). A W(n,n) is a Hadamard matrix and a W(n,n-1) is equivalent to a conference matrix.t
