MATLAB: Problem in saving array in txt file

hi, I want to save this array in file but I did not get what I want

ex.

x={'RCIN'    'AFGN'    'RGGA';'RCIN'    'RQDM'    'RGGA'};

in fact my data is more larger, but are of this type.

when run this code:

outfid=fopen('web.txt','wt');
for i=1:2
  for j=1:3
    fprintf(outfid, '%c ',x{i,j} );
  end
  fprintf(outfid,'\n' );
end

I get web.txt as

R C I N A F G N R G G A 
R C I N R Q D M R G G A

But I need it as in array: 'RCIN' 'AFGN'…….

please, who can help me , I suffered from this problem since long time

thanks in advance, huda
