Loop Files from a Directory
显示 更早的评论
Hi, I want to loop files in a folder. I used the following method:
datadirs = dir('../Inputdata/URL2');
dircell = struct2cell(datadirs)' ;
filenames = dircell(:,1);
datafilename =strcat('../Inputdata/URL2/',filenames(3)); %just a try.
fid = fopen(datafilename);
It gives me an error message.
But when I used:
ff = '../Inputdata/URL2/2017032312_8952.txt'; %(The same as the "datafiename").
fid = fopen(ff);
It worked.
WHY!!!
How to fix the problem?

What files you want to open in a folder? Do they have any extension?
@Qingsheng Bai: instead of making up your own complicated and buggy syntax, you would be much better off simply copying the examples shown in the MATLAB documentation:

Valid point Stephen. Edited my answer.

Change
datafilename =strcat('../Inputdata/URL2/',filenames(3));
to
datafilename =fullfile('../Inputdata/URL2',filenames{3});
and if you're only playing with txt files, then why not
datadirs = dir('../Inputdata/URL2/*.txt');
