While loop constraint has to be true for every variable

Hello,

I work on a matlab script in which i have an input of 50 parts, numbered 1 to 50. For all of these parts i calculate a specific distribution which gives an attribute to this specific part (the ARF1-value).

In the wile loop, this attribute for every part has to be higher than a target. How can i model that if this attribute is lower than the target, the s-value of this part goes one point higher and if it is higher than the target, this s-value stays the same and this part leaves the while loop? I now have this but it does not work.

Thanks in advance:

while AFR1(i)<TargetAFR;

        s=s(i)+1; 

    for i=1:length(s);

   FR(i)=poisscdf(s(i)-1,m(i)*t(i));

   AFR1(i)=((m(i)/M)*FR(i));

    end

    Results(end+1,:) = [iteration:iteration;s;AFR];
    iteration = iteration + 1;

end

s=s(i)+1;

Is going to overwrite s. Surely you want

s(i) = s(i) + 1

instead.

This line

Results(end+1,:) = [iteration:iteration;s;AFR];

is also suspicious. The first part of that concatenation will always just resolve to 'iteration', though it doesn't do any harm, it's just un-necessary.

Thanks, you're right it has to be s(i)=s(i)+1

However, even when i have this it keeps on iterating forever without reaching the target. The s-values remain zero except for the 50th one, this one goes to infinity..

You need to show more code. I just took a glance at what you posted to find obvious problems, but a second glance shows there are a number of things that don't make sense.

Where is 'i' coming from in your while loop indexing? You are using i lower down as the index for your for loop so don't reuse a variable like that if i is defined higher up. Also if it is you need to include that code because I have no idea what s(i) represents outside of the for loop that loops around i.
