{{alias}}( [out,] W )
|
||
|
Returns an accumulator function which incrementally computes moving minimum
|
||
|
and maximum absolute values.
|
||
|
|
||
|
The `W` parameter defines the number of values over which to compute moving
|
||
|
minimum and maximum absolute values.
|
||
|
|
||
|
If provided a value, the accumulator function returns an updated moving
|
||
|
minimum and maximum. If not provided a value, the accumulator function
|
||
|
returns the current moving minimum and maximum.
|
||
|
|
||
|
As `W` values are needed to fill the window buffer, the first `W-1` returned
|
||
|
minimum and maximum values are calculated from smaller sample sizes. Until
|
||
|
the window is full, each returned minimum and maximum is calculated from all
|
||
|
provided values.
|
||
|
|
||
