lonarr or -1L
Parameters
- ind1 in required type=lonarr or -1L
array of indices where -1L
indicates an empty set of indices- ind2 in required type=lonarr or -1L
array of indices where
-1Lindicates an empty set of indices
Keywords
- count out optional type=long
set to a named variable to return the number of elements in the union
