Hi!
Below is a workflow based on groupcounts function:
clear
load noisydata.mat
figure
subplot(211)
plot(dataset, 'o')
title("noisy data")
% Filtering based groupcounts
[GC, GR] = groupcounts(dataset) ;
denoisedData = dataset(ismember(dataset, GR(GC>10))) ; % group that has count less than 10 will be removed
subplot(212)
plot(denoisedData, 'o')
title("denoised data")
Hope this helps
