u^:n Extended |
initial writing: 2004-03-22 |
u^:(<m) , previously an error, is defined as follows:
| u^:(i.m) y | if m is a non-negative integer | ||
| u^:(i.k) y | if m is _ or , where k is the smallest positive integer such that (u^:(k-1) y) -: u^:k y | ||
| u^:_1^:(<|m) y | if m is negative |
Moreover, the monads {&x^:a: or {&x^:(<_) for integer list x and the dyads {~^:a: or {~^:(<_) are supported by special code.
See the dictionary entry for u^:n for examples.
