Hi,

I would like to re-create a NaN array like the attached image below. Meaning, the size of the array will be 1x187, but inside the array I rather each cell be a mx1. Example 2x1, 10x1, 3x1, 13x1, 4x1, etc.

Any help is appreciated.

I was not 100% clear on what you wanted. Is this output right?

% Input array
C = {["Mercury","Gemini", "Apollo"; ...
      "Skylab", "Skylab B","ISS"], ...
     ["Mercury","Gemini";
      "Skylab","Skylab B"]}
C = 1×2 cell array
    {2×3 string}    {2×2 string}
% Output array
out = cellfun(@(x) nan(size(x,1),1)    ,C,'UniformOutput',false)
out = 1×2 cell array
    {2×1 double}    {2×1 double}
