1. Introduction. A square matrix H of order h all of whose elements are pth roots of unity is
called a Hadamard matrix (H (p, h) matrix) if HHCT= hI. It is known [4] that H (2, h) matrices …

This Report studies Hadamard matrices of order 20. Proof is given that there are exactly
three classes of such matrices; the work done to show this result is discussed, and the …

matrix H of order 4t is associated in a natural way with an SBIBD with parameters (4t-192t-l …

The Hadamard product of two matrices multiplied together elementwise is a rather neglected
concept in matrix theory and has found only brief and scattered application in statistical …

An Hadamard matrix H is a. square matrix of ones and minus ones whose row (and hence
column) vectors are orthogonal. The order n of an Hadamard matrix is necessarily 1, 2 or At …
