<array<series>> output = <series>.split(<number> Window Length, <number> Window Overlap)
This function returns an array of windows from a data series. Each window is size Window Length and they overlap by Window Overlap samples. These arguments are both given in samples.
Example:
var myWinArray = mySeries.split(100, 25);
for(var i = 0; i < myWinArray.length; i++)
myWinArray[i] = myWinArray[i].abs();
The example above accesses each window series in the split array, takes the absolute value, and replaces the window with the new absolute value window.
