create a matrix y of size (n+1) whose last column's elements are the summation of the elements of all the other columns and last row's elements are the summation of the elements of all the other rows; where 'n' is the size of the input matrix 'x'.
for example x=[1 2 3;4 5 6;7 8 9] then y=[1 2 3 6; 4 5 6 15; 7 8 9 24; 12 15 18 45]
