Join Join data sets for joining two data sets to form the difference, for example. Syntax model.result().dataset().create(<dtag>,"Join"); model.result().dataset(<dtag>).set(property, <value>); Description model.result().dataset().create(<dtag>,"Join") creates a join data set feature named <dtag>. The following properties are available: Table 7-43: Valid Property/Value Pairs for Join Data Sets name Value Default Description data none | data set name None The first source data set. data2 none | data set name None The second source data set. expr String data1-data2 When method is general: The way the evaluations in the first and second data sets is combined. data1 and data2 can be used as symbols for the values from the two data sets, respectively. method difference | differencenorm | explicit | general | product | quotient | sum difference How to combine the results from evaluating in the two source data sets. solutions all | one all Whether to expose one or all solutions from the first data set. solutions2 all | one all Whether to expose one or all solutions from the second data set.
