ArrayMath.movMax


Usage

movMax(interval)

Description

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

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

interval(Mandatory)The window size.

The current ArrayMath object.
