how to write a matrix to text file with loop name of .txt

Let's say, I have a code like this:

for i = 1:size(cell,2)
     data = cell{i}; %kx3 matrix
    dlmwrite('name_change_acoording_to_each_loop.txt', data, 'delimiter','\t','newline','pc','precision',15);
end

I want to write a matrix to .txt file. And The result will be a set of .txt file, with the name is according to the value of i

Example:

cell={[1 1 1] [1 2 3;3 2 1] [4 5 6;7 8 9;1 1 1] [2 2 2;3 3 3]};

-Loop 1: i=1 ---> the result of text file is : 1.txt

-Loop 2: i=2 ---> the result of text file is : 2.txt

-Loop 3: i=3 ---> the result of text file is : 3.txt

-Loop 4: i=4 ---> the result of text file is : 4.txt

Finally, I will have 4 text files with the name is: 1.txt ; 2.txt ; 3.txt; 4.txt

But my code doesn't provide the result as my expectation.

How can I do that? How can I fix my code? Thanks

sprintf('%d.txt',i) % this would be your filename inside the loop

You mean my modified code like this:

for i = 1:size(cell,2)
     data = cell{i}; %kx3 matrix
    dlmwrite('name_change_acoording_to_each_loop.txt', data, 'delimiter','\t','newline','pc','precision',15);
    sprintf('%d.txt',i) % this would be your filename inside the loop
end

for i = 1:size(cell,2)
    data = cell{i}; %kx3 matrix
    filename=sprintf('%d.txt',i); % this would be your filename inside the loop
    dlmwrite(filename, data, 'delimiter','\t','newline','pc','precision',15);
end
