Hi
I have attached my scatter poit figure and I want to make a 2 or 3 clusters from them.
This is my code;
for i = 1:size(MeanEchos,1);
for j = 1:size(MeanEchos,2);
scatter(blob_area{2,j},MeanEchos{2,j},'x');
set(gca,'xscale','log');
grid on;
xlabel('Blob Area');
ylabel('Mean Echo Intensity');
xlim([0 10^5]);
ylim([0 5])
end
end
I would be greateful if anyone would be able to help me.
Thanks in advance

If you have statistical and machine learning toolbox, then try kmeans(): https://www.mathworks.com/help/releases/R2020b/stats/kmeans.html
