[Azzi Abdelmalek]

a=dlmread('a.txt');
b=dlmread('b.txt');
c=[a,b];
dlmwrite('c.txt',c);

[Azzi Abdelmalek]

a=dlmread('a.txt')
b=dlmread('b.txt')
header='   x              y              z'
c=[a b]
fid=fopen('file.txt','w')
fprintf(fid,'%s \r\n',header)
myformat='%12.8f %12.8f %12.8f \r\n'
fprintf(fid,myformat,c)
fclose(fid)

Dear Azzi,

After combining them I have added headers for them, now I should import these data to excel spreadsheet but it is failed? Many thanks

Similarly to dpb's answer you can also use load:

>> c = [load('a.txt'),load('b.txt')];
