my fid is a positive value but I could not find where the file was created. How can I locate the file in MATLAB

Thanks

在 MATLAB Online 中打开

It will be in the current folder - just look at the top of MATLAB and it will show it to you. It's not very robust programming to do that. It's far more robust to specify the folder so you know exactly where the file gets saved to, rather than just going into whatever the current folder happens to be.

folder = 'C:\Users\Public\Documents'; % or wherever.
baseFileName = 'test1.dump';
fullFileName = fullfile(folder, baseFileName);
[fileID, message] = fopen(fullFileName, 'w')
