Redheffer matrix
text:
In mathematics, a Redheffer matrix, often denoted A n as studied by Redheffer (1977), is a square (0,1) matrix whose entries aij are 1 if i divides j or if j = 1; otherwise, aij = 0. It is useful in some contexts to express Dirichlet convolution, or convolved divisors sums, in terms of matrix products involving the transpose of the n t h Redheffer matrix.
