Scilab Function

intersect - returns the vector of common values of two vectors

### Calling Sequence

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

### Parameters

- `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

### Description

`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)`.

### Examples

    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))
