Hello everyone, I hope you are doing well.

I have the four cells and each cell has four column .

i applied the following algorithm which find the histogram of second column of each cell, and find the unique value and count and repeat the values based on count.

At the output i only get single column in the cell, but i want the the 2nd preprocessed column with all other column which present in the input of each cell. How can i do it in MATLAB

K=4
for i = 1:K
    T = C1{i}(:,2);
    h1(i)=histogram(T,100000,'BinLimitsMode','manual','BinLimits',[0 3e8]);
    BindataF{i}=h1(i).Data;
    T1=BindataF{i};
    Values=unique(T1);
    counts=histc(T1(:),Values);
    val{i}=Values;
    cnts{i} = counts;
end
for k =1:K
    c = cnts{k};
    v = val{k};
    z=k+1;
    for j=z:K
        temp = val{j};
        cnt_temp = cnts{j};
        for m = 1: length(v)
            for n = 1: length(temp)
                if v(m)== temp(n) 
                    c(m)=c(m)+cnt_temp(n);
                    temp(n)= nan;
                    cnts{j}(n) = nan;
                end
            end
        cnts{k}(m) = c(m);
        end
        val{j} = temp;
        
    end
end
fnRM=@(v,c)repmat(v,1,c);  
for i=1:numel(val)
    ix=isfinite(cnts{i});
    C{i}=cell2mat(arrayfun(fnRM,val{i}(ix),cnts{i}(ix),'UniformOutput',false).');
    Cluster{i}=C{1,i}.';
end

@dpb I was offline, i accept the previous answer. But now we have four column in which we are processing second column, and produce the output, but i want the remaining column as same as in the input

Again, don't try to describe, SHOW a small example input and expetced output...it's much faster for us and more likely to result in the actual result described--I really don't follow the above precisely and don't have time to try to puzzle it out.
