Delete double cell array entries

How can I delete double entries in a cell array? I don't want to use a loop. For example I have:

CellArray={[1 2 3] [1 2] [3 5 6 7] [1 2] [2 4] }

And as a result I want to get this:

NewCellArray={[1 2 3] [1 2] [3 5 6 7] [2 4] }

Thank you very much and have a nice day!

CellArray={[1 2 3] [1 2] [3 5 6 7] [1 2] [2 4] };
m=max(cellfun(@numel,CellArray));
v=cellfun(@(x) [x  inf(1,m-numel(x))],CellArray,'un',0);
[~,ii]=unique(cell2mat(v'),'rows');
CellArray=CellArray(ii)

This solution works really fine and fast! Time needed for my loop: 1.24 seconds Time needed with the one line solution from Friedrich below: 0.3 seconds Time needed with your solution: 0.07 seconds! :) Thanks so much!

Hi,

one line:

NewCellArray  = cellfun(@str2num, unique(cellfun(@num2str, CellArray,'UniformOutput',false)),'UniformOutput',false)

This solution works very good and I like that it is only one line. But in my case I prefer the faster solution from above. Thank you!

 CellArray={[1 2 3] [1 2] [3 5 6 7] [1 2] [2 4] };

 NewCellArray  =  [CellArray(1:3) CellArray(5)];

 CellArray is just an example, I guess his array is much bigger.

Yes, that's the problem. My cell array can have thousands of entries.
