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);
