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 ]
