WebDescription. example. Idx = knnsearch (X,Y) finds the nearest neighbor in X for each query point in Y and returns the indices of the nearest neighbors in Idx, a column vector. Idx has the same number of rows as Y. Idx = knnsearch (X,Y,Name,Value) returns Idx with additional options specified using one or more name-value pair arguments. dhp east dunbartonshire https://sarahnicolehanson.com
