How to write multiple files (.dat or .txt) with consecutive file names in matlab

I have the following scenario:

for t = 1:10 % As time goes from 1 to 10.

           for i = 1:10 % As position goes from 1 to 10.

                 u(i) = some operation

           end


s = u'; % Just getting a transpose so i can read the data better.

save ("File(i).txt', 's', '-ascii', '-tabs');
                                             
                                       % I know this doesn't work. I need a help with this.

end

Desired output:

File1 : with data at t = 1 and i = 1:10.
File 2: with data at t=2 and i = 1:10;
and so on.


How to save multiple files using a for loop, or any other method would would also work.

You're almost there.........
txtfile=['File' num2str(i) '.txt']; % Need to convert index to string
save (txtfile, 's', '-ascii', '-tabs');

Take a look at this (I just found it today):
http://matlab.wikia.com/wiki/FAQ

Hit Ctrl+F, and search for this: 'How can I process a sequence of files?'
