One can use num2cell:

N_ROWS = 5; N_COLS = 2;
A = rand(50,2);
B = num2cell(reshape(A,N_ROWS,N_COLS,[]),[1,2]); % B is 1x1x10 cell array

What this does is turn your input array into 5x2 "slices" stacked along the 3rd dimension.

You can add a squeeze(B), B = B(:) or a reshape(B,[],1) at the end if you need the output as a column vector.

That is what mat2cell does:

A = rand(50,2); % example matrix
N = 10; % number of cells in which to split the first dimension
result = mat2cell(A, repmat(size(A,1)/N, 1, N), size(A,2));
