SOM - please help

Dear Sir/Madam

I have employed:

"classes = vec2ind(y)" in my code for unsupervised SOM clustering where "y = net(x)"

For my dataset "classes" is a matrix of 1 x 2643

Then I try to print out the output from "classes" considering only column 1 to 10:

"h=classes (1:10); h"

The output on the screen is:

"h =

40 40 40 40 40 40 40 40 40 40"

but I could not understand what this means.

Please, could you help me with this. Regards, Naghmeh

Sorry, I haven't used MATLAB's form of SOM. The one I wrote circa 1982 is buried in my cellar somewhere and probably won't be found while I am still alive.

Right now my plate is full, no ... overflowing, so I cannot help.

Sorry, I just don't have the time.
