I can I duplicate raws of variables?

I have imported an xls file spread sheet and I need to replicate six time each raw.

Ex. a1,b1,c1,d1 a2,b2,c2,d2 .................. ..................

Into a1,b1,c1,d1 a1,b1,c1,d1 a1,b1,c1,d1 a1,b1,c1,d1 a1,b1,c1,d1 a1,b1,c1,d1

a2,b2,c2,d2 a2,b2,c2,d2 a2,b2,c2,d2 a2,b2,c2,d2 a2,b2,c2,d2 .................. ..................

try this standard method

 a=[1:3];
 b=[];
 for n=1:6
 b=[b a];
 end

Thank You for your answer, it works and I will keep it in mind :-) but actually it is not what I need. The editor does not allow me (Or I am not used to it) to well explain my problem. Here is an image explaining my problem

hi Maria, you add a semicolon to the above code :

   %....
   b=[]
   for n=1:6
   b=[b;a];
   end
