Hello,
I have a 9 matrices of size 1x21996,
how can I divide the 9 matrices to be 6 of 1x3666 each?
I tried this but it only saves the last iteration
for a=1:numel(B)
A=mat2cell( B{a},[1],[3666 3666 3666 3666 3666 3666])
end
thanks.

Are you sure you need a cell array? If the chunks have the same size a numerical array is much more efficient:
A = rand(1, 21996);
B = reshape(A, [], 6);
Now use B(:, k) to access the k.th subvector.
If you really need a cell:
C = num2cell(reshape(A, 6, []), 2);
