WebJan 7, 2016 · If we denote the matrix with all entries equal to 1 by M, then A = y M + ( x − y) B, with B = A ( 1, 0). Now M is n times a projection (on the vector with all 1 's), so if we diagonalize, we obtain. S − 1 M S = n ( 1 0 0 0 n − 1, n − 1). because only one entry of the matrix on the RHS is not a multiple of x − y. WebThe determinant is a special number that can be calculated from a matrix.
