hi,

I got the indices of clusters of my data. I would like to see the result with drawing. i.e I hope to see the clusters graphically.

can do that?

thanks in advance

A search for "cluster" refined by Graphics in the File Exchange finds twenty contributions.

... and the statistical toolbox

thanks, I visited that link and run plotcluster: http://www.mathworks.se/matlabcentral/fileexchange/31710-plotclusters-m

but I confused with the first input of this function, the author said that the first input must be n*2 or n*3 and do not know exactly what are the elements of n*2 or n*3 if n is the number of observations , is that meaning I have to creat array with size 6*2 , because i have for examplr 6 observations and the matrix be data=[1 1;2 2 ; 3 3; 4 4; 5 5; 6 6]

I'm not sure, if that proper or not.

Look at the Description at that link. It describes exactly what each of the parameters means.

*clusters* in that data because your data is uniformly spaced. Or there are 6 clusters with just one point in them, or one big cluster with 6 points. You don't really have aggregation or clumping of any of the points.

Huda, when I answered your other question, I suggested that you run 'doc linkage' and gave you a link to the web doc for that function. At the bottom of that page, you can see examples of two different plots. Are you asking for a plot that is not on that page?

i saw , but I think scatter do not work with my case. please see comments below with image analyst

thanks

Why not just use the scatter() function? If that doesn't work, then explain why not, and use more words to do it.
