intersect

Find set intersection of two vectors

Syntax

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,:)).
