setxor
Returns the elements contained in either of two sets, but not in their intersection.
Syntax
setxor(a,b)
setxor(a,b,'sorted')
setxor(a,b,'stable')
setxor(a,b,'rows')
[c,ia,ib]=setxor(a,b)
Inputs
- a, b
- The sets whose exclusive union is to be formed.
- 'sorted'
- Returns elements of the exclusive union in ascending order.
- 'stable'
- Returns elements of the exclusive union in their original order.
- 'rows'
- Returns distinct rows as opposed to distinct elements.
Outputs
- c
- The exclusive union of a and b.
- ia, ib
- a(ia) and b(ib) are disjoint sets whose union is c.

Comments
When repeated elements occur in an input, the last index will be used.
