csvwrite increment file name

hi everyone,

i have problem with this code

    clear all;

f = 'F:/Maya/pengenalan pola/tugas image retrieve/image';
fileList = dir(fullfile(f,'*.jpg'));

path_save = 'F:/Maya/pengenalan pola/tugas image retrieve/data pixel';

for i = 1:length(fileList)
   I{i} = imread((fullfile(f,fileList(i).name)));
   out{i} = mat2cell(I{i}, ones(120/60,1)*60, ones(120/60,1)*60, 3);
   [ra{i} rb{i} rc{i}] = cellfun(@(x) unique(x(:,:,1)), out{i} , 'un', 0);
   [ga{i} gb{i} gc{i}] = cellfun(@(x) unique(x(:,:,2)), out{i} , 'un', 0);
   [ba{i} bb{i} bc{i}] = cellfun(@(x) unique(x(:,:,3)), out{i} , 'un', 0);
rr = csvwrite(['r' num2str(i) '.txt'],rc{i});
   gg = csvwrite(['g' num2str(i) '.txt'],gc{i});
   bb = csvwrite(['b' num2str(i) '.txt'],bc{i});
end

returns error

??? Error using ==> csvwrite Too many output arguments.

Error in ==> histogram at 22 rr = csvwrite(['r' num2str(i) '.txt'],rc{i});

how can i fix this?? really need ur helps, plzzz :(

<http://www.mathworks.com/help/techdoc/ref/csvwrite.html csvwrite>() does not output anything. What output value were you expecting that you would store in rr, gg, or bb ?

[Rusmaya Luthfina]

rr, gg, bb would be a double array..

thx u Mr. Roberson

[Walter Roberson]

What double array are you expecting in each case? csvwrite() writes out data, so if it did return anything at all, the sorts of thing it would return might be error codes or counts of the items written or something similar.

If you are expecting that rr and so on would be assigned the data written, then do not try to assign them the output of csvwrite(): just assign rr = rc{i}; gg = gc{i}; bb = bc{i};
