Hi I have 25000 file txt and I wrote the below code to read all the txt extract all the value and than I will use for some calculation.

The problem is that at the moment I have valC that is composed by 25000cell and each cell is composed by <14x1>cell. I would like to remove one level or extract the 14value of each cell for 25000times in a single 25000x14cell. Is it possible?

fileList = dir('*.txt');
nameFile = cell(1, numel(fileList)); % Pre-allocate!
for i = 1:numel(fileList)
  NAME = fileList(i).name;   % [EDITED]
  nameFile{i} = NAME;
  fid = fopen(NAME);
  valC(i) = textscan(fid, '%s', 'delimiter', ',');
  val  = valC;
  fclose(fid);
end

在 MATLAB Online 中打开

fileList = dir('*.txt');
nameFile = {fileList.name}; % Pre-allocate!
data     = cell(numel(fileList), 14);
for i = 1:numel(fileList)
  fid = fopen(nameFile{i});
  valC = textscan(fid, '%s', 'delimiter', ',');
  data(i, :) = transpose(valC{1});
  fclose(fid);
end
