I'm working with k-means in MATLAB. And here is my code:

k=input('Enter a number: ');
[g c] = kmeans(cobat,k,'dist','SqEuclidean');
y = [cobat g]
[s,h]=silhouette(cobat,g,'SqEuclidean') %Show the silhouette graphic
%Show the plot3D graphic
Colors=hsv(k);
PlotClusters(cobat,g,c,Colors)

When I run it, it works anyway, but why " [s,h]=silhouette(cobat,g,'SqEuclidean')" can't be shown?

When I deleted this line: Colors=hsv(k); PlotClusters(cobat,g,c,Colors)

The silhouette graph can be shown.

What should I do so all the graphs can be shown?

Your help means a lot to me, thank you.

Call hold on after your silhouette() call. 'hold on' prevents the current axes from being cleared after each plotting command.

[s,h]=silhouette(cobat,g,'SqEuclidean') %Show the silhouette graphic
hold on;
%Show the plot3D graphic
Colors=hsv(k);
PlotClusters(cobat,g,c,Colors)
doc hold
