MATLAB: Different cells with different array sizes and outputting them to textfile

export rows different multiple sizes to text file dat fileMATLAB

I have multiple cells (10+) containing arrays of different sizes and I would like to export them as seperate rows in a .dat file (seperated by a space). What is the most easy way to do this?
Cells are ordered like:
Columns 1 through 2
    [5x1 double]    [5x1 double]
  Columns 3 through 4
    [9x1 double]    [6x1 double]
  Columns 5 through 6
    [4x1 double]    [5x1 double]
I have tried it with dlmwrite, fopen fprint fclose, etc. but none will give me what I want, which is just the vectors pasted into a .dat file seperated by a space.
So
Cell1vector1 Cell1vector2...etc... Cell2vector1 Cell2vector2... etc...

assuming that cellArray is the variable storing your different cells; then:
fid=fopen('outputfilename.txt','w');
if (fid==-1)
  error('could not open outputfilename.txt for writing.');
end
for idx=1:numel(cellArray)
  fprintf(fid,'%f ',cellArray{idx}); % pay attention to space after %f
  fprintf(fid,'\n');
end
fclose(fid)
