{{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.
Parameters
----------
out: Array|TypedArray (optional)
Output array.
W: integer
Window size.
Returns
-------
acc: Function
Accumulator function.
Examples
--------
> var accumulator = {{alias}}( 3 );
> var mm = accumulator()
null
> mm = accumulator( 2.0 )
[ 2.0, 2.0 ]
> mm = accumulator( -5.0 )
[ 2.0, 5.0 ]
> mm = accumulator( 3.0 )
[ 2.0, 5.0 ]
> mm = accumulator( 5.0 )
[ 3.0, 5.0 ]
> mm = accumulator()
[ 3.0, 5.0 ]
