Just call csvread or dlmread 5 times, then concatenate, then call csvwrite

m1 = csvread(filename1);
m2 = csvread(filename2);
m3 = csvread(filename3);
m4 = csvread(filename4);
m5 = csvread(filename5);
mOut = [m1;m2;m3;m4;m5];
csvwrite(fileNameOut, mOut);

Is there an easy way for use a for loop with this method to csvwrite() hundreds of files?

You can use a for loop

outputFolder = 'c:\whatever';
if ~isfolder(outputFolder)
    mkdir(outputFolder);
end
for k = 1 : 200
    data = GetNewDataSomehow();
    baseFileName = sprintf('File #%2.2d.csv', k)
    fullFileName = fullfile(outputFolder, baseFileName);
    writematrix(data, fullFileName);
end
