arrange columns side by side using matlab

Hii experts, i have 5000 .txt file in a directory that contains single column data. i want to arrange them side by side seqentially to make a mxn matrix file.

My files serial number starts from 1.txt 2.txt.....5000.txt

Are the data numeric? Is the number of values the same in each file?

n = 5000; % number of files to read
basefilename = 'temp'; % change as necessary

M = []; % preallocate if you know the number of values in each file
for i=1:n
    f = [basefilename num2str(i) '.txt'];
    if isfile(f) % verify file exists (as a precaution)
        M(:,i) = readmatrix(f);
    end
end
