How to save output results from loop in a vectors?

So this is my code:

threeminutes_Facebook_newsfeed;

h=[0:0.5:179];

for idx=1:length(h)

threshold=h(idx);

m =find(threshold-1<=x & x<=threshold);

Y(idx)=sum(y(m));

end

count_zero=0;

count_value=0;

i=1;

while i<length(Y)

    if (Y(i)==0)  
        count_zero=count_zero+1;
        i=i+1;
        while Y(i)==0  && i<length(Y)
        count_zero=count_zero+1;
        i=i+1;
        end

        if i<(length(Y))
        count_zero
        count_zero=0;
        end

        if i==(length(Y))  &&   Y(length(Y))~=0 
                            count_value=1;
                            count_value
                            count_value=0;
        elseif   i==(length(Y))  &&   Y(length(Y))==0             
                            count_zero=count_zero + 1;  
                            count_zero
                            count_zero=0; 
        end

    else
        count_value=count_value+1;
        i=i+1;
        while Y(i)~=0 && i<length(Y)
        count_value=count_value+1;
        i=i+1;
        end
        if i<(length(Y))
        count_value
        count_value=0;
        end

        if i==(length(Y))  &&   Y(length(Y))~=0 
                            count_value=count_value+1;
                            count_value
                            count_value=0;
        elseif   i==(length(Y))  &&   Y(length(Y))==0             
                            count_zero=1;  
                            count_zero
                            count_zero=0; 
        end

    end
end

I have multiple results for count_zero and count_values. I would like the results are in vectors, for exaple all results of count_zero in vector a, and all results from count_values in vector b. I know it is possible just cannot do it. Please help! Thanks in advance!

1. Initialize two vectors a and b as a=[],b=[];
2. Now add this line (a = [a count_zero];)at a line or end of loop from where you need to store the value of count_zero from.
3. Do the same for b,(b = [b count_value];) .
4. This will store all your values of count_zero in vector a and count_value in vector b.
5. Below is the example for your reference.

Given a collection of points, return the indices of the rows that contain the two points most distant from one another. The input vector p has two columns corresponding to the x and y coordinates of each point. Return ix, the (sorted) pair of indices pointing to the remotest rows. There will always be one unique such pair of points.

So if

p = [0 0]

[1 0]

[2 2]

[0 1]

Then

ix = [1 3]

That is, the two points p(1,:) and p(3,:) are farthest apart.

%Then
% ix = [1 3]
%That is, the two points p(1,:) and p(3,:) are farthest apart.

function ix = mostDistant(p)
 
 [len,~] = size(p);
 dist = []; % vector I am storing distance for each combination of points
 idx = []; % indices of points for which the distance is stored in vector dist
  for i = 1: len
      for j = 1:len
          
          distance_between = (p(j,1)-p(i,1))^2 + (p(j,2)-p(i,2))^2;
          distance_between;
          dist = [dist; distance_between; distance_between]; % Appending the distance 
          idx = [idx ;i ;j]; % Appending the indices
      end
      
  end 
  mat = [dist idx];
  h = sortrows(mat,1,"ascend");
  
  [len2 ,~] = size(h);
  iwx = [h(end-1,2) h(end,2)];
  ix = sort(iwx);
end
