MATLAB: Extract and realign cells into new cell

Question

Hi all,

I have a cell array 'cellA' which contains cell:

cellA = 
    {2x1 cell}    {2x1 cell}    {2x1 cell}
    {2x1 cell}    {2x1 cell}    {2x1 cell}
cellA{1}
ans = 
    [12x2 double]
    [30x2 double]

All arrays in cellA are same size. Now what I want is to extract each double array and put them in a new cell, so I will have 2 new cells:

cellB = 
    [12x6 double]
    [12x6 double]
cellC = 
    [30x6 double]
    [30x6 double]

I know I can probably write a for loop to do this, but is there a faster, vectorized way?

Thanks!

Answer 1

A = cell(2,3) ;
for i = 1:2
    for j = 1:3
        A{i,j}{1,1} = rand(12,2) ;
        A{i,j}{2,1} = rand(30,2) ;
    end
end
B = [A{:}] ;
B1 = mat2cell(cell2mat(reshape(B(1,:),2,3)),[12 12]);
B2 = mat2cell(cell2mat(reshape(B(2,:),2,3)),[30 30]);
