How to compare a value to a matrix and repeat the comparison after increasing the value

I am working on an algorithm that compare the vectors' peak locations with the average vector peak location and excluding vectors that their peaks are located over 10 Hz away from the average vector. The average vector peak then it will be included otherwise if the number of vectors included is less than 20 vectors then I should increase the difference in peak location by 10 Hz until it reaches or exceeds 20.

I am not able to create a loop that recompare (RA is the difference between peak locations in Hz) the peaks after increasing V from 10 Hz by 10 Hz every time until the number of vectors I1>=I.

Can you please help me create a loop the recompare RA with V (for k = find(RA<=V))

V=10; I=20; I1=0;
for k = find(RA<=V);
    if     numel(k)>=I
           RI=RV(:,k); I1=numel(k);
    elseif   I1<I
            V=V+10;
        else
            break;
        end
    end
end

Hi Ahmed,

Could you explain the problem statement more clearly and what the variables represent in the code as I am not able to understand the problem clearly.

[Ahmed Makki]

In a simpler way, for a given values of A and B. If [array]<=B and if the number of elements in the array that satisfy this condition are equal or greater than A then y=x+1 else increase B by 1 and recompare it with the array elements until both conditions apply.

Hi Ahmed,

Based on your explaination

while(1)
    % find number of elements that satisfy [array]<=B 
    numOfElements = length(find(array<=B));
   
    % Check if they are greater than A
    if(A<=numOfElements)
        y=x+1;
        break;
    else
        B=B+1;
    end
end

It worked thank you very much for your help

Do you want to find the candidate peaks using islocalmax then select those candidates that are within 10 of your average?

Thank you. I know how to determine the peaks locations, but the problem is in creating a loop that increases the number that we compare with until it satisfy conditions. Please find above a clearer discription of the problem that made
