#: i.@(*/) Improved |
last updated: 2000-06-23 |
The monad #: i.@(*/) computes the odometer function.
The phrase is now "recognized"
(implemented by special code),
improving its performance in time and space
on non-negative integer vector arguments.
Time and space comparisons are as follows:
ts=: 6!:2, 7!:2@] v=: 2 3 5 7 11 13
