ParzenWindow
ParzenWindow[x]
represents a Parzen window function of x.
Details

- ParzenWindow is a window function typically used for antialiasing and resampling.
- Window functions are used in applications where data is processed in short segments and have a smoothing effect by gradually tapering data values to zero at the ends of each segment.
- ParzenWindow[x] is equal to
.
- ParzenWindow automatically threads over lists.
