intersect

intersect — returns the vector of common values of two vectors

Calling sequence

[v, [ka,kb]]=intersect(a,b)

`a`	: vector of real numbers or strings
`b`	: vector of real numbers or strings
`v`	: row vector of real numbers or strings
`ka`	: row vector of integers
`kb`	: row vector of integers

intersect(a,b) returns a sorted row vector of common values of two vectors of a and b.

[v,ka,kb]=intersect(a,b) also returns index vectors ka and kb such that v=a(ka) and v=b(kb).



A=round(5*rand(10,1));
B=round(5*rand(7,1));

intersect(A,B)
[N,ka,kb]=intersect(A,B)

intersect('a'+string(A),'a'+string(B))
