I can't clearly understand that the matlab function: "Idx = knnsearch(X,Y)" searches for nearest neighbours. But what method it uses for search? I read default method is eucledain but I didn't input any method. I just used [Idx, b] = knnsearch(X,Y,'K',10). So will it use eucledainas the default method?

'euclidean' (default)
Yes, the defualt method is euclidean.

You need not to mention. Thr meaning of default is, if you don't use/ mention the method name default method will be used.
