file_0.csv

在 MATLAB Online 中打开

Hi,

I am trying to import multiple csv files into Matlab (.csv extension) but I am keep getting an empty structure.

Following online suggestions I used the following line of code:

d = dir('/Users/file_*.clv');
images = arrayfun(@(f) csvread(f.name), dircontent, 'UniformOutput', false);
image = cat(3, images{:});

For some reason seems like Matlab doesn't read the data. I got the following when I checked the size(image). I was expecting a 3D array instead.

ans =
       0     0

Below the code I used with the .csv extension:

d = dir('/Users/file_*.csv');
images = arrayfun(@(f) csvread(f.name), dircontent, 'UniformOutput', false);
image = cat(3, images{:});

I got the following error:

>> mult_csv  
Error using csvread (line 35)
File not found.
Error in mult_csv>@(f)csvread(f.name)
Error in mult_csv (line 8)
images = arrayfun(@(f) csvread(f.name), dircontent, 'UniformOutput', false);

Any ideas?

P.S. I attached an example of my csv files.

I've edited my post to make things more clear. I also attached a file as requested.

Oh, so this is just a continuation of import-multiple-csv-files-in-matlab.

For some reason, I missed that you commented there (There was a problem yesterday where the activity feed stopped updating for a few hours). I've now updated my answer.

   % Please save all files name in symmetrically before doing the operation
   %keep in all one folder, so you avoid the confusion with others files
   % names for example f1,f2,f3...
   %Save the folder of files in the current directory
   path_directory='folder_name_here'; 
   % Pls note the format of files,change it as required
   original_files=dir([path_directory '/*.file_extention_format']); 
   for k=1:length(original_files)
      filename=[path_directory '/' original_files(k).csv];
      file(k)=csvread (filename);
     % Next do your operation and finding
