omitting data from a cell array

I have a cell array

    A = cell 1: 1,2,5,6 (4x1)
        cell 2: 3, 5.5, 6.4, 3, 7.2 (5x1)
        cell 3: 2, 13 (2x1)
        cell 4: 15 (1x1)
        cell 5: 2, 3.25, 6.35 (3x1)

I want to get rid of any cell that has under 3 elements, so the new cell array should have only cells 1,2,5

Thanks

n={ [1 2 5 6] ,[3 5.5 6.4 3 7.2] ,[2 13] ,15, [2 3.25 6.35] }
out=n(cellfun(@numel,n)>=3)

Thank You! What if I want to merge any cell with under 3 elements to the cell following it. For example merge cell 3 into cell 4, so the new cell 3 consists of 2,13,15 (3x1)
