No. The cell array is required to be rectangular; the content of some cell can be empty as you have, but the cell array itself can't be jagged.
>> c=cell(2) % build a minimal cell array
c =
[] []
[] []
>> c(4)=[] % try to shorten the second row
c =
[] [] []
>>
As you see, Matlab has let you eliminate the cell, but it now is a vector, not 2D array.
You could encapsulate each row into another cell that can be variable-length, but that's another level of indirection in addressing to get to the data.
Where's the problem, specifically, as is other than simply the visual representation isn't neat?
