running a loop and saving separate files

Hi I am running a loop and saving each file separately.

The syntax I am using is

for i = 1:10
RUN PROGRAM
save(sprintf('datafile_%02d',i), 'phi')
end

So this means I am expecting all the phi's to be saved in different filenames. But I only get the most recent (overwritten?) and I do not get 10 separate files.

No, i is changing so the filename is changing. Try to split it up

for k = 1 : 10
    % code to RUN PROGRAM and change phi...
    % Now save this phi in a new file.
    filename = sprintf('datafile_%02d.mat', k);
    message = sprintf('About to save phi into new file %s.', filename);
    uiwait(helpdlg(message));
    save(filename, 'phi');
end

Now see if the filenames are all the same or different.

Hi, I get an error message

undefined function or variable 'k'

how do i proceed?

I found the error. There was a 'clear' function at middle part so everything got erased. It is ok now. Thanks for your help.
