functions:JOIN

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]                       | 1  2  1 | 
                                        | 3  4  2 |
 then M = JOIN(X,Y)  makes a matrix M = | 5  6  3 |
                                        | 7  8  4 |
                                        | 9 10  5 |
