ST_intersectioni

Find the set intersection of two vectors and returns an index vector with the positions in a. (All the elements that are in a and b)

c = ST_intersectioni(a, b)

Return Value

c*is an index vector with the intersection of *a and b. If an intersection doesn’t exist the functions returns 0.

Parameters

a

a is a string or real matrix.

b

b is a string or real matrix.

Example

* ST_intersectioni([2.1,3.3,5,4.1,7], [2.1,4.1,9])
   1.000    4.000
*
* ST_intersectioni(["one", "two", "three"], ["two", "four", "five"])
   2.000
