Function: knn
Description: computes a running mean over (2k+1) consecutive values of a given vector. To have the same length at the beginning and at the end the first and last value are repeated k times.

Usage: m = knn (x, k)
Input:
x n vector of the obervations
k scalar range of the running mean
Output:
m n vector containing the smoothed values

Example:

randomize(1)
knn (uniform (8), 2)
Result:
