Grouping set of numbers with different size of rows

Hi all,

I would like to group set of numbers into a container that I can use later in for loops: The first column are the set numbers. Example:

groupNum=[
1 61 32 624 15 2000;
2 25 3 635;
3 19 20 49 30;
4 56 28; 
5 29 51 60;
]

    for i=1: size(groupNum,1) % for 1 to 5 in this case
      for i=1: size(groupNum,2) % for 1 to number of column in the set
          %do something
      end
  end

That code will result in error because the size of the matrix is not consistent. Any advice would be much appreciated.

Thanks in advance.

Thanks for reply. I tried that before posting this and its not working: e.g.

aaa={1 2 3;1 2}

will give error: Dimensions of matrices being concatenated are not consistent.

Good night! See @Jan's answer.

Maybe:

groupNum = {1, [61 32 624 15 2000]; ...
            2, [25 3 635]; ...
            3, [19 20 49 30]; ...
            4, [56 28]; ...
            5, [29 51 60]}
