Saving to text file from cell array

Dear colleagues,

we have a cell array like the one below, we obtained from a txt file:

[34] [12] 'xxx'
[3]  [1]  'www'
[21] [2]  'qwe'
[11] [12] 'awk'
[34] [x]  'sed'

we just want to save it as a matrix text file with the same dimensions once again, afer having applied some replacement loops.

dlmwrite doesn't work (we're not dealing with matrixes)
save has unsupported Ascii..

fprintf ! It's the whole day we're struggling with it. Here is our code:

column1 = num2cell(colum1_from_txtfile)
column2 = num2cell(colum2_from_txtfile) 
column3 = cellstr(colum3_from_txtfile)

M = [column1 column2 column3]

% our loops

fid = fopen('another_txtfile', 'wt')
fprintf(fid, '%d%d%s\t\n', M)

??? Error using ==> fprintf
Function is not defined for 'cell' inputs.

We guess the whole problem is about the value types we're using in the fprintf argument (%s %d ..).

We would be absolutely happy if anybody could provide as with suggestions!

Best,

Udiubu & Co.

Is this a different question than your earlier http://www.mathworks.com/matlabcentral/answers/31231-txt-file-to-cell-array-to-text-file

?? If so then it would be best to indicate the difference, as otherwise someone is likely to mark it as a duplicate question that requires merging.

for K = 1 : size(M,1)
  fprintf(fid, '%d%d%s\t\n', M{K,:});
end

Hi Walter,

Sorry to have made some caos with duplicates.

Indeed, we also thought about a loop over the first dimension, but we get some random ordering of different sizes of numbers and letters, like below:

34 12 x
120(which is 'x' in Ascii, we assume) 120 3 1
119 119 21

Thanks for your kind help.

Best,

U-
