Adding semicolon and comma and saving it into .txt file

I have a vector (2x6001) and I want to save it to into a .txt file,. But before saving it , I also want to add a semicolon after every even position and a comma after every odd position:

Let's say:

x=(x1,x2,x3,x4,x5,...)

and I want sth like this:

x=(x1,x2;x3,x4;x5,...)

How can I do this?

I don't have access to the writematrix function, only dlmwrite

I tried delimiter, but all the data will get the same delimiter.

Try this low-level code:

-----------------------------------------

x = randi(9,[1,2*6001]); % ACTUAL DATA

fileID = fopen('data.txt','w');

for k = 1:2:numel(x)-1

fprintf(fileID,'%g,%g;',x(k),x(k+1));

end

fclose(fileID);

-----------------------------------------

Enjoy!
