Dear All, It is my first time using this mail list to post a question. And I sincerely hope that this will not bother any subscribers. So far as I know, there are functions like union( ), which can help to combine two sets of discrete data. But what if the data sets are with continuous data. For instance, I got three sets like [2, 4], [5, 6], [3.4, 5.5]. I wonder if there is a quick solution to recognize their union is [2, 6], and return the size of this union 6-2=4 to me. The similar demand is for the intersection operation. If you get any idea, please inform me. Thanks in advance!
