JOIN function
| Syntax: |
m = JOIN(x,y)
|
The arguments of the JOIN function must both be
vectors. JOIN produces a matrix with 3
columns. The first column is the intersection of x
and y, that is, if you enter
m=JOIN(x,y) then m[*,1] is the same
as x/&y, where /& is the
intersection operator.
m[i,2] is the index of
x from which m[i,1] was
taken, and m[i,3] is the index of y
from which m[i,1] was taken. If the vector arguments
are ordered, the JOIN function will proceed much faster than if they are unordered.
Example
Suppose that you have two vectors:
X = [0;1;2;3;4;5;6;7;8;9;10], Y = [1;3;5;7;9]
