hey guys!

I have a question

a= 1 0 0 1 1 0 2 0 2 0 3 3 4 1 4 0 7 1 7 2 9 1 6 3 7 2 10 1 10 3 8 1 10 6 13 5 8 3 13 0 7 4 5 5 3 0 2 1 2 0 2 1 3 0 1 2 1 0 0 0 2 0 1

How would be the easiest way to make sure there is no numbers under 5? I don't want to filter the numbers under 5 away, but keeping them in the vector by adding them to other columns.

so that the sum(a)= 200, which is the total now.

Adding them to which columns?

No clue what the above is attempting to describe--give a small starting and ending result; (probably by scaling down the target sum?)

One of many, many possible ways:

a = [1 0 0 1 1 0 2 0 2 0 3 3 4 1 4 0 7 1 7 2 ...
    9 1 6 3 7 2 10 1 10 3 8 1 10 6 13 5 8 3 ...
    13 0 7 4 5 5 3 0 2 1 2 0 2 1 3 0 1 2 1 0 ...
    0 0 2 0 1];
your_mat = a(a > 5);
your_mat(1) = your_mat(1) + sum(a(a<=5));

Sorry for the bad explanation, english is my primary language.

I need the data for some statistiscs,(poisson) which in this case messes my results up,if i have values that are under 5. But i don't want to lose any of the data, i just want to add them so that there are none under 5 left. The length of it doesnt matter, just as long as the sum=200 and there is none under 5.

That still does not explain what you want. Would like the data to be spread over several columns or a single one? There is effectively, infinitely many ways to answer your question. Furthermore, if you want to do statistics and just change your data like that not only are you introducing bias but completely changing your distribution.

I have an exemple below.

we are instructed to not have values below 5, so i am trying to do that :)

does not matter if its spread over several columns or if its just in one. That i do know how to change myself. I do not know to effectivly add the columns to eachother so that i don't have a single one below 5. the order does not matter as long as it isnt shuffled or anything like that.
