Main function, which opens and closes the file:
fid = fopen(FileName, 'w');
if fid == -1, error('Cannot open file'); end
Recursive(fid, 17);
fclose(fid);
And the recursice function:
function Recursive(fid, Num)
Num = Num - 1;
if Num == 0
return;
end
fprintf(fid, '%d\n', Num);
Recursive(Num);
end
Or you open the file in the recursive function for appending:
function Recursive(Num)
fid = fopen(FileName, 'a');
if fid == -1, error('Cannot open file'); end
fprintf(fid, '%d\n', Num);
fclose(fid);
Num = Num - 1;
if Num > 0
Recursive(Num);
end

maby your fclose(fid) is in the loop
fid = fopen('filename.txt', 'w');
for k=1:10
v=(1:k), %example
fprintf(fid, '%f\t',v);
fprintf(fid, '\n',[]);
end
fclose(fid);

I think you can add this code inside your function just after cluster1
fprintf(fid, '%f\t',cluster1);
fprintf(fid, '\n',[]);
and call your function
fid = fopen('filename.txt', 'w');
F=devide();
fclose(fid);
