[C#]	public ArrayMath movMin(int interval);
[VB]	Public Function movMin(interval As Integer) As ArrayMath

Replaces each element of the ArrayMath object by its moving minimum.

The interval parameter specifies the window size for computing moving average. The moving average is computed as the minimum of the current element with the previous (interval - 1) elements. No moving minimum 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.

The current ArrayMath object.
