function summa = eja(A)
summa = 0;

c is fixed as the last column. So in
[r c] = size(A);
for i = 1:r
summa = summa + (sum(A(r>=c)));
end
you are trying to sum the values of just those rows that are equal to or greater than the number of columns.

@Abdur Rob Yes. That's what I said! I showed the lines that were giving the trouble. The following will do the sum you want:
function summa = eja(A)
summa = 0;
[r, c] = size(A);
for i = 1:r
summa = summa + sum(A(i,i:c));
end
end
