| 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}) | |
| Input: | ||
| 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) | |
| Output: | ||
| z | m x k x d1 x ... x dn array | |
x=1:4 y=2:5 mknn(x,3,y)
