The intersection function intersect of sets in Matlab
intersect
Set intersection of two vectors
Syntax
c = intersect(A,B)
c = intersect(A,B,‘rows’)
[c,ia,ib] = intersect(…)
Description
c = intersect(A,B)
returns the values common to both A and B. The resulting vector is sorted in ascending order. In set theoretic terms, this is A B. A and B can be cell arrays of strings.
c = intersect(A,B,‘rows’)
when A and B are matrices with the same number of columns returns the rows common to both A and B.
[c,ia,ib] = intersect(a,b)
also returns column index vectors ia and ib such that c = a(ia) and c = b(ib) (or c = a(ia,:) and c = b(ib,:)).
