Save multiple run result of script

Hi i'm writing a code with matlab, i wonder if there is a way to save the result of my script every time i run it.Example if i run this code multiple times i want to get all different outputs in my vector or file in case of using save function.

    s=[]; 
    s=fitness(D,vect);

Because every time i execute, it overwrites the last result.

Thank you.

EDITED

numOfRuns = 5;
for n=1:numOfRuns
  s = fitness(D,vect);
  save(['result_data_run_number_' num2str(n) ',mat'],'s');
end

I tried it but i get the error 'Argument must contain a string.' in save because of 's'

Sorry, my bad. It should have been

 save(['result_data_run_number_' num2str(n) ',mat'],'s');

I fixed it but then i still have the same problem because the loop executes in one run and i get same results

You will get different results only if you change some of your code. I only showed you how to run a code multiple times and store the outcome in different mat files.

Put the part of the code you want to repeat inside for loop and save should be at the end of the loop.

Thank you, my fault, so obvious but i was stuck with the idea that i have to click on the run button every time.

An alternative to using a loop: download my FEX submission nextname, which will generate the next name each time you call it. Simply put this in your script to generate the filename:

name = nextname('result','_1','.mat')
