Usage

`[C#] ` | `public ArrayMath movStdDev(int interval);` |

`[VB] ` | `Public Function movStdDev(interval As Integer) As ArrayMath` |

Description

Replaces each element of the ArrayMath object by its moving standard deviation.

The**interval** parameter specifies the window size for computing moving average. The moving average is computed as the standard deviation of the current element with the previous (interval - 1) elements. No moving standard deviation can be computed for the first (interval - 1) elements, because there are insufficient previous elements. So the first (interval - 1) elements will be replaced with NoValue.
