| 6 | mean:Computes the outcome of a recursion using the function `fn' in which the\ |
||
| 7 | variable `v' is replaced successively by values `v1', ..., `v2'. <p>\ |
||
| 8 | In the second syntax, the values are given with respect to each item in\ |
||
| 9 | the list `v1,v2,...'. <p>\ |
||
| 10 | The function `fn' should use the variable `last' to indicate the value of the previous \ |
