Split array in sub arrays according to growing value in first row

I have an array where the first row has growing intiger numbers. How can I split the array according to those values.

Example: This

 [ 1 1 1 2 3 3

   x x x x x x 

   y y y y y y ]

Should become something like this

 [ [1 1 1  [2  [3 3

    x x x   x   x x

    y y y]  y]  y y] ]

What is the purpose? Splitting arrays is usually not recommended.

Hi

m=[1 1 1 2 3 3;randi(10,2,6)];
c={};
for i=min(m(1,:)):max(m(1,:))
   c{i}=m(:,m(1,:)==i);
end
