Concatenate cell of arrays

I have a cell(1 row x many columns) of arrays( many rows x 5 columns).

 cell = [ 3 x 5 double, 2 x 5 double]

I want to write them all to a file row by row. So my text file will look like

1 2 3 4 5
1 2 3 4 5
1 2 3 4 5
2 2 3 4 5
2 2 3 4 5

where the first 3 rows come from the 1st cell and the next 2 rows from the 2nd cell for example. I have tried this but it does not work

fprintf(fid,'%d %f %f %f %f\r\n', bbs{1,1:end});

So i just found out about dlm write but it only accepts a matrix input. My input is a cell of matrices.
