Hello All,

I am been trying to download the files which are stored in the seessions of web app server to my local pc.

I have used "uiputfile" function as well but that does not seems to work. I am able to see that file is stored in session and just that I am not able to download it.

Also I want to create a hyperlink though which user can download .xlsx files direclty to their folder. (This is also connected to this question)

I am using matlab 2021b version.

Let me know if you have have any solution to this.

在 MATLAB Online 中打开

uiputfile just creates a full path for downloading file in server side, so you need to execute writetable (for .csv and .xlsx) and copyfile (for other file formats).

Here is a sample to download a PDF file from Web App.

[file,path] = uiputfile('test.pdf');
if isequal(file,0) || isequal(path,0)
  disp('User clicked Cancel.')
else
  str = which('test.pdf', '-all');
  if ~isempty(str)
    copyfile(str{1}, fullfile(path, file))
  end
end
