Dataset.mat

Hello Everyone, I hope you are doing well. I have an array named as Dataset. I have replace 0 in for those values which has histogram count less than 50 percent of maximum value.

Now in my new array Dataset Has some Values which are equal to 0; I want to delete 0 in array and replicate the matrix from the start to complete matrix length for example the Dataset has length 137x1.

        Batchdata=Dataset;
fig=figure; set(fig,'visible','off');
h=histogram(Batchdata,10000);
sumofbins=max(h.Values);
size_MP=round(50/100*sumofbins);
ValueofHistogram= h.Values;
Bindata=h.Data;
Binedges=h.BinEdges;
Binedges(end) = Inf;
deleted_data_idx = false(size(Bindata));
for i=1: length(ValueofHistogram)
    if ValueofHistogram(i)<size_MP;
        deleted_data_idx(Bindata >= Binedges(i) & Bindata < Binedges(i+1)) = true;
    end
end
close(fig);
Dataset(deleted_data_idx,:)=[];
