Hello Matlab's community,

I would like to edit k-means clustering algorithm in order to add a check before the merge of an observation into a cluster.

In particular, I have a NxN matrix where "N" is the number of input database's observations. Within this matrix there is the value "+1" when the two observations are "linked", and "0" otherwise. In this situation, the k-means clustering algorithm should join an observation into a cluster if and only if: there is at least one observation inside the arrival cluster which is "linked", namely has the value "+1" in the aforementioned matrix", with the observation in question.

I will appreciate any advise

Thanks!
