MATLAB: How to open multiple .txt files

Question

Hi all,

I have certin number of txt files with different names (ex: 5, 10, 15, 20, 25, 30, 35, 40, 80, 120, …)

I want to open them using a loop.

Any help would be appreciated.

If all the files have the same structure/data format, you can use datastore to merge them:

fileNames = {'t1.txt', 't2.txt', 't3.txt'}
ds = readall(datastore(fileNames)); % change other properties if needed

otherwise, you can use readtable within a loop

fileContents = {};
fileNames = {'t1.txt', 't2.txt'};
for i = 1:numel(fileNames)
    fileContents{i, 1} = readtable(fileNames{i});
end
