| 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 | |
