Dea All, I'm wondering how we can control of the length(size) of each elemnt in a cell array(Since each elemnt is a matrix itself) .
Thanks

C - your cell array
out = cellfun(@size,C,'un',0)

Or, as usual: "cellfun('size', C, 2)" to get a vector of the lengths of the 2nd dimensions.

Not sure I understand. You control what goes in so of course you control the length of it because you know what you put in. For example in this cell array with 2 cells, I put a 1x4 array into the first cell, and I put a 3x8 array into the second cell:
ca{1} = rand(1,4)
ca{2} = rand(3,8)
I controlled the lengths of each individual cell (4, and 3*8=24) because I controlled what I put in there, and I controlled the length of the cell array (2) because I created 2 cells. Am I missing something here (about why you're confused)?

But you got an answer to something you didn't ask. They showed you how to DETERMINE (or "find out") the size of your cell, not CONTROL it. There is a difference in definition between determine and control. I showed you how to control the size (like you asked) whereas they showed you how to determine what you already have (i.e. find out what you have already in existence but not how to specify or control the size in the first place).
