Hi all, how to converting cell array containing more cell array (have different sizes) to one cell matrix? For example:

C=
  {1x1 cell}
  {1x3 cell}
  {1x2 cell}

The matrix size inside the cell array is different, thus I cannot use vertcat or horzcat function. I try to use catpad function, but it only concatenate the cell individually.

  F = {{[0.04,0.2,0.56;0.31,0.67,0.22]},{...
    [6+6j,7+3j,8-6j;6+8j,7-6j,3-3j],...
    [5+6j,8+5j;6+8j,7-6j;5+6j,3-9j],...
    [1-6j,1-5j;1-8j,1+6j;1-6j,1+9j]},{...
    [16+6j,7+3j,8-6j;6+8j,7-6j,3-3j],...
    [5+6j,8+5j;6+8j,7-6j;5+6j,3-9j]}}
  
  dim = 2
for kk = 1:numel(F)
    for ii = numel(F{kk}):-1:2
            for oo = 1:ii-1
                R1 = catpad(dim,F{kk}{:})
                R2 = catpad(dim,F{ii}{:})
                break
            end
    end
end

If I add another cell into the cell F, I get an error. How to do this?

Thank you in advance
