So #of independent elements are (n-1)(n-1) Using guassian elimination it will be difficult to calculate rank, based on what I have matrix's properties can we guess the rank?

1) For sure M(&&) is not 0. But In this case, I still don't know how to compute rank? 2) lest's assume rank is 1, in this case how many independent elements doe I have?

Hello all, I have a question: assume in matrix M(n*n), each element M(i,j) of matrix is computed as M(i&)*M(&j) / M(&&) where M(i&) is the summation of ith row, and M(&j) is the summation of jth column and M(&&) is the summation of all M(ij) for i=1..n and j=1..n. Now I want to know what is...
