(summation i=1 to s summation r=1 to 7 q^2ir/Mi*Mr)-1/log(n)
s=3
Mi for ist row is 2,second row is 4,third row is 1
Mr is 1 for all cases
n=7

[m k] = size(A);
i1 = (1:m)';
r = 1:k;
Mi = [2; 4; 1];
Mr = 1;
out1 = bsxfun(@rdivide,i1*r.*q.^2,Mi)*Mr;
out = sum(out1(:)) - 1/log(n);
ADD
out2 = max(out1) - 1/log(n);
