.txt ( and not the automatic.mat) using save with num2str option

Hi all, I have this code:

 for l=1:nelettrodi
   for j=l+1:nelettrodi
        for k=j+1:nelettrodi

        V_ = V_I(l)+V_I(j)+V_I(k);   
        save(['V_', num2str(l), num2str(j),num2str(k)],'V_')

My problem is that this save the variable V_ in a .mat file, but I want it to be a .txt. I tried this:

 save(['V_', num2str(l), num2str(j),num2str(k)]'.txt','V_')

and it seems like it does the jobs. I say it seems since it saves it as a .txt file but the content of this file is just some line with strange symbols. I need a .txt file because another program has to use this variable and can read only .txt. Thank you very much for your time, Giorgio.

You need to add '-ascii' as a final parameter. Also you can make your code cleaner:

filename = sprintf('V_%d%d%d.txt' l, j, k);
save(filename, 'V_', '-ascii')

Note: if l, j, or k can exceed 10, then you can generate ambiguous file names with what you are doing now. For example, j=1, k=12 cannot be told apart from j=11, k=2 .

and of course nelettrodi<=10
