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:

XX_X1_XXX.dat:

1 1

2 2

3 3

XX_X2_XXX.dat

4 4 4

5 5 5

6 6 6

XX_X3_XXX.dat

7

8

9

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

Bigdata.dat

1 1 4 4 4 7

2 2 5 5 5 8

3 3 6 6 6 9

Thanks a lot

load XX_X1_XXX.dat; % this will put the values in Variable X1
load XX_X2_XXX.dat; % this will put the values in Variable X2
load XX_X3_XXX.dat; % this will put the values in Variable X3

bigdata=[X1 X2 X3];
