hi guys , i have used this code to write this cell array into a text-file, but the the text-file i got is adding some abnormal numbers beside the numbers contained in the cell array!!!!
C5 = X;
fid5= fopen('X_file.txt', 'w');
for h=1:217
fprintf(fid5, '%s\t %s\t %s\t %f\t ', C5{h}{:});
fprintf(fid5,'\t');
fprintf(fid5,'\n');
i got like this which is exist here"X-fileoutput" end fclose(fid5);

Your cells all contain character vectors, but you include a %f element, which tells MATLAB to expect a numeric element there. The 45.0 that you see are the %f representation of char(45) which is the '-' that just happens to be present in your character vectors.

@Walter Roberson Thanks a lot ,i got it .
fprintf(fid5, '%s\t ', C5{h}{:});
this works well but still i have a little issue when reading the output file in Excel is taking only 16384 columns instead of 17817 columns, however in Notepad all displayed till 17817 ?

There is nothing you can do about that. Excel has a limit of 16384 columns.
You could write as columns, using a different "sheet" for each variable.

@Walter Roberson yes; because of the limited columns issue in Excel. So I will reverse the file. Thanks for your help and your quick response! I really appreciate it !

@Walter Roberson friend, I want again ask you how could I add a header line which has 17814 columns of string format( vector of 17814*1), means start where those float numbers start as in "X.png" and cell 1 and 2 and 3 will have no header?
i know that i have to use again fprintf (fid5,'%s\t',header{...}.....} and i read also about append but i can't figure out a proper command that can do that?

temp = vertcat(header, X{:}) .';
fmt = [repmat('%s,', 1, length(X)), '%s\n'];
fprintf(fid5, fmt temp{:});
This will put the header as row headers, and each of the 217 entries in X will become columns, each of length 17814.

@Walter Roberson friend, I have tried your code but still getting an error as follow
*Error using vertcat CAT arguments dimensions are not consistent.
*Error in endfile (line 22) temp = vertcat(header, X{:}).'; *

header was a column vector so i turn it to row vector of size 1*17814 and still dimension not consistent!.

this is the code I tried:
fid5= fopen('fileX.txt', 'w');
temp = vertcat(header, X{:}).';
fmt = [repmat('%s,', 1, length(X)), '%s\n'];
fprintf(fid5, fmt, temp{:});
fclose(fid5);

@Walter Roberson hi friend could you see the error i got ?

Your X is length 17817 per entry but you are trying to put on a header of length 17814 . You need to put in those last 3 header entries.
