I'm working with k-means. And this is the graph of mine.
It looks messy. The red and blue are mixed. What do you think? It is because the file I used? Or the clustering isn't working properly?
Here is my code…
load cobat.txt k=input('Enter a number: ');% CLUSTER (PUSH BUTTON)
[g c] = kmeans(cobat,k,'dist','SqEuclidean');y = [cobat g]% SHOW THE GRAPHIC
%# show points and clusters (color-coded)
clr = lines(k);figure, hold onscatter3(cobat(:,1), cobat(:,2), cobat(:,3), 36, clr(g,:), 'Marker','.')scatter3(c(:,1), c(:,2), c(:,3), 100, clr, 'Marker','o', 'LineWidth',3)hold offview(3), axis vis3d, box on, rotate3d onxlabel('x'), ylabel('y'), zlabel('z')
