save in a new file using 'save' command

I have a program which I am applying on 50 files. I want to now save output for everytime I run the program in a new file.

Currently, I am using "save outfile er2 -ascii"

But everytime program runs it replaces outfile with the current output parameters. But I want in a new file i.e. I want a file for every run of program.

Please help me out

Do not use command syntax:

For looped code follow the examples given in the documentation:

Thanks for your reply. Could you please explain a little bit. I am somewhat new to MATLAB SO it will be really helpful.

If your function is called in a loop then follow the examples here:

https://www.mathworks.com/help/matlab/import_export/process-a-sequence-of-files.html

If your function is not called in a loop then you could download my FEX submission nextname:

https://www.mathworks.com/matlabcentral/fileexchange/64108-next-available-filename

and use it something like this:

D = 'absolute/relative path to the directory where the files are to be saved';
F = nextname(fullfile(D,'outfile'),'01','.mat');
save(F,'er2')

It will ensure that the filename is unique and unused each time you save the data.

I don't recommend using save for writing text files. For writing text files you should use a more appropriate function:
