Using the FPScript function [b]IndexNot()[/b] and [b]IndexAnd()[/b], you’ll get the indices thar are in the one but not in the other dataset. Here is an example:
[code]
Dim aa, bb, cc, dd
aa = {1,3,5,7, 11, 4, 34}
bb = ValuesInInterval(aa, 0, 10, EVENT_INDEX)
cc = ValuesInInterval(aa, 0, 5, EVENT_INDEX)
dd = IndexNot(cc, NumberOfValues(aa))
IndexAnd(bb, dd)
[/code]
The variable bb contains the indices of the values within the interval 0 to 10. The variable cc contains the indices of the values within the interval 0 to 5.
Use the [b]IndexNot[/b] function to get all indices of the values which are not in the interval 0 to 5. The result of the [b]IndexAnd[/b] function is a data series with the indices which appear in both arguments. In this case the result is a data series with the indices of values within the interval ]5,10].
