A Technique for Computing Minors of Binary Hadamard Matrices and Application to the Growth


A technique for computing all possible minors of order (n − j) × (n − j) of binary Hadamard matrices with entries (0, 1) is introduced. The method exploits the property ST S = 1 4 (n+1)(In +Jn) of such matrices S, and also the symmetry and special block structure appearing if one forms DT D, where D is a submatrix of S. Theoretically, it works for every… (More)
