Function: mknn
Description: mknn gives an array containing the indices of the k nearest neighbors of each element in matrix y with respect to x. The parameter y is optional, if it is not given, x will be taken for y. As a measure of distance the squared euclidean distance is used.

Usage: z = mknn (x, k{, y})
y m x p x d1 x ... x dn array
x n x p x d1 x ... x dn array
k scalar (number of neighbors)
z m x k x d1 x ... x dn array
