ArrayMath.movMin


Usage

movMin(interval)

Description

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

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

Arguments

ArgumentDefaultDescription
interval(Mandatory)The window size.

Return Value

The current ArrayMath object.
