If ALL is specified, the Intersect function intersects nonduplicated elements as usual, and also intersects each duplicate in the first set that has a matching duplicate in the second set. The two sets specified must have the same dimensionality....
The Intersect function performs an intersection of the specified time series over the entire length of each time series or over a clipped portion of each time series.
The optionalALLflag retains duplicates. IfALLis specified, theIntersectfunction intersects nonduplicated elements as usual, and also intersects each duplicate in the first set that has a matching duplicate in the second set. The two sets specified must have the same dimensionality. ...
