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

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

From the images, it seems that the results are correct. It clearly shows two clusters. I am glad to be of help!

Great. Thanks a lot!
