Extracting data from a structure

I have performed DCT on an image(256×256) and the the compressed data is saved in a file. When i open this file in workspace, the compressed file is a 32×32 structure, with cells, each containing binary digits of different lengths(some more than 128) for each cell. I would like to extract these digits and align them in 1 matrix, however i do not know how to do this. Can you please advise me on how to solve this problem in matlab.

I am not sure I understand your question. But if what you mean is that you have a cell array of structures and that you want to extract one element from each structure, then you could do as follows:
a.whatever = 125; %some structure
your_cell = cell(10,5);
your_cell(:) = {a};
your_mat = cellfun(@(x) x.whatever,your_cell);
