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 replace 0 with the Values already present in the array.
For example the array consists of value
34.9609375000000
37.9882812500000
34.9609375000000
These Values should be in placed of 0's
How can i do it in Matlab
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,:)=0;

array=[34.9609375000000
37.9882812500000
34.9609375000000];
Dataset(deleted_data_idx,:)=repmat(array,1,size(Dataset,2));
presuming
numel(array) == sum(deleted_data_idx)

You're missing the point -- how to calculate that number of repetitions is where the hint and ceil() come into play.
