This question doesn't make any sense. Could you please provide the relevant part of your code and describe in more detail what your question is?

I believe the question is how to find the optimal number of clusters for KNN.

It's not an answer. I unaccepted it. I have used knnsearch(). I'm attaching a simple demo for (x,y) data. If you need a demo, post your image and explanation in a new question.
