MATLAB: How to construct an array with varying dimension

cellformatrixstructure

I want to save some data using a "for loop". Within each iteration, I will get a 2D matrix (which I want to save). the size of the matrices is NOT the same, i.e. first 10*10, then 23*23, next 20*20 and so on (no pattern between the sizes). I clearly cannot use a 3D matrix to save the data since the third dimension is not constant. I cannot save them manually/separately either since there is a lot of 2D matrices (this is actually why i am putting it in a for loop). I also do NOT know the size of the largest 2D matrix.
what can I use to do the above? cell? structure?
tnx in advance

Yes. Use a cell array. That's what it's meant for. See the FAQ for a good explanation and some good illustrative examples: http://matlab.wikia.com/wiki/FAQ#What_is_a_cell_array.3F
