I'm using som for clustering in my project. I want the image to be clustered into three clusters. so in this case how to set the values for 'd1' and 'd2' in the function 'selforgmap' ?

Kohonen's SOM algorithm is for UNSUPERVISED clustering. For supervised clustering he recommends his LVQ and LVQ2 algorithms
Nevertheless, you could try
1. Set d1 or d2 to be 3 and vary the other
or
2. Try initsompc
>> lookfor som
>> lookfor LVQ
Hope this helps.

Try using VLFEAT matlab implementation for Clustering, it has many algorithms with tutorial and example codes. You can easily see visually the clusters with different K.
