Hey,

I want to execute a script (main) in a loop which gives me a different result (solvertime) every time I run it and write this result into a vector with the size of the Number of runs.

NumOfRuns = 3;
results=zeros(1,NumOfRuns);
for i=1:NumOfRuns
    main;
    results(i)=solvertime;
end

For some reason it gives me this vector. Help is much appreciated.

can you share your code ?

Regarding your flag ("I found out that the answer to this question was that "i" was somewhere in the script. so no one in this forum could know the answer. delete this please"):

We tend not to delete questions (especially those that have received valid attempts at an answer) unless there are very good reasons for doing so. Often the underlying reason is that the content should never have been made public in the first place. Because it is hard to say if something is usefull to some random passer-by in the future, we tend to want to keep content as-is. I don't see any such reason for deletion in your post, so I'm going to remove the flag. If you disagree, feel free to explain in a comment why you believe this question should be deleted. Just in case you were planning to delete the question content: I can easily restore it from this Wayback Machine capture, so you don't have to bother.

Something does not make much sense: given NumOfRuns = 3, why does results have 26 columns?

I suspect that the script also contains a variable named results, in which case there are two main solutions:

rename one/both of those variables so that they have different names
turn your script into a function (preferred approach).

hey,

renaming the variables in this script (as shown above, not main) have the same results

I guess it has something to do with script (main) because it is quite complex and it interferres with that loop function in some way

This is why experienced MATLAB users avoid scripts for any real work. Scripts are fun and easy to play with, but if you want reliable, repeatable, reuable code then functions/classes are the only way to go.
