concatenate data files horizontally into one file

Hello,

I have several data files with the same number of rows and I need to concatenate them all into one big file. For example, we might have the following two files:

data1.dat:

1 1

2 2

3 3

data2.dat

4 4 4

5 5 5

6 6 6

and I want to concatenate data files into one horizontally into one file like below.

Bigdata.dat

1 1 4 4 4

2 2 5 5 5

3 3 6 6 6

Thanks a lot

alldata = [];
for K = 1 : NumberOfFiles   %looping over all of the files
  thisfile = whatever %name of file #K
  thisdata = load(thisfile);
  alldata = [alldate, thisdata];
end

Thanks.

But my files' name is like this: xxx1xx.dat, xxx2xx.dat and xxx3xx.dat

So how can I do that?

alldata = [];

for K = 1 : NumberOfFiles %looping over all of the files

thisfile = sprintf('xxx%dxx.dat');

thisdata = load(thisfile);

alldata = [alldate, thisdata];

end
