Problem 3

%Creates a 6x6 matrix A_66 in which every element is the product of its two indices
%Then finds the mean and standard deviation
for i = 1:6
  for j = 1:6
    A_66(i,j) = i*j
  end
end
fprintf('mean of A_66 =%1.2\nstdev of A_66=%1.2f\n', mean(A_66(:)), std(A_66(:)))
Mean = mean(A_66(:));
Dev = std(A_66(:));
