x=[4 5 5 5 5 5 5 5 5 ];

and,

sum(x)=44 is alway same.
As a result,

            x{1}=[4 4 4 5 5 5 5 6 6]
            x{2}=[4 4 5 5 5 5 5 5 6]
            x{3}=[4 4 5 5 6 6 6 8]
            x{4}=[4 4 5 5 5 5 7 9]
            x{5}=[5 5 5 6 6 7 10]
                     .
                     .
                     .
                     .
                     .
