table to excel code update

in matlab 2020 my code was working very good when i update to 2021 my code didn't work any more and it says Error using cellfun

Input #2 expected to be a cell array, was struct instead.

my code was i don't know what is change in matlab 2021a ? and how to correct it

to convert table with struct to excel sheet

if true
  n = cellfun(@length,result.bw);
  f = repelem(result.fileName,n);
  s = vertcat(result.bw{:});
  s = struct2table(s);
  s.fileName = f;
  writetable(s,'myexcel.xlsx');
end

Not sure what bw is, but if it's an image length(bw) will give you the largest of either (1) the number of columns in the image, or (2) the number of rows in the image. I really don't know what you're after because there are no comments to give example expected results. If you want to write f, just write f. Why are you adding it to a structure and then trying to write the structure???

So edit your original post and

1. add comments to your code and
2. add result in a .mat file with the paperclip icon

save('answers.mat', 'results');

Then I can work on fixing it.

So whatever was storing cell array of struct array into the table object is storing something else instead. We would need the code that is creating the bw variable in the table object.
