% I need to write cellArray into text file as 3 tab space after the first column and 2 tab space between the numeric numbers. I need to get 8 numbers after the dot for numeric data.

C = {'p.1', 38.141794059793398, 31.983184186130529, 1.751451095529832e+03; ...
10, 38.094455446389709, 31.940682658186898, 1.779530219110660e+03; ...
'ab1', 38.162956465159276, 32.019563510560964, 1.542875077314675e+03; ...

% It took me time to edit the data in a clean syntax. Please do this by your own.
fid = fopen(FileName, 'w');
if fid == -1, error('Cannot open file for writing: %s', FileName);
Ct = C.';
fprintf(fid, '%s %.8f %.8f %.8f\n%f %.8f %.8f %.8f\n', Ct{:});
fclose(fid)
Or with \t instead of teh spaces depending on what "tab spaces" means.

I'm sorry Simon. I don't know well about fprintf. But the result is still same when I replace '%.8f' by '%d': like; fprintf(fid, '%s %.8f %.8f %.8f\n%f %d %.8f %.8f\n', Ct{:});

@sermet: considering this and all of your other questions related to fprintf precision:
now would be a good time to read the documentation:
The lovely people at TMW spent a lots of time writing it, and it contains lots of useful information!
