Reading tables from the asc files in Matlab

Hello,
I have more than 400 asc files and I have to combine them all to make 4 tables in Matlab. I am searching on internet and I didn't find anyway to import the data from the asc file with the Matlab. I only saw answers as I need to convert it to .txt file for .csv files. But since I have a lot of them, can someone tell me how to solve this problem?

If they are text files, one option using readtable is in the Text Files documentation section, specifically using the name-value pair 'FileType','text'.
Example —
T = array2table(randi(9, 5, 4))
writetable(T, 'RandomFile.asc', 'FileType','text')
which 'RandomFile.asc'
T1 = readtable('RandomFile.asc', 'FileType','text')
.
EDIT — Corrected typographical errors.

As always, my pleasure!
If they all have the same variables, you can vertically concatenate them in a loop —
Example —
for k = 1:3
T = array2table(randi(9, 5, 4))
FileName = sprintf('RandomFile%03d.asc',k)
writetable(T, FileName, 'FileType','text')
end
Files = dir('*.asc');
for k = 1:numel(Files)
FileNames{k,:} = Files(k).name;
end
FileNames
for k = 1:3
Tk{k,:} = readtable(FileNames{k}, 'FileType','text');
end
Tk
Tc = cat(1,Tk{:})
I never previously realised that this sort of demonstration was possible using the online Run feature!
