 Once compilation is complete, you can launch any function in parallel on the 
 cluster. For example, let's suppose you have the following function 'foo':
 
-  ```
-  >> function [u v] = foo(a, b, c)
-  >>     u = a + b + c;
-  >>     v = a * b * c;

 If you want to compute 'foo(1, 3, 4)', 'foo(2, 3, 5)' and 'foo(8, 3, 0)' then
 simply do:
 
-  ```

 You will get u = {8; 10; 11} and v = {12; 30; 0}. More generally you can launch 
 any function on a set of N arguments. If an argument is the same for all
