Over (⍥
) is a dyadic operator which takes two functions and produce a function (⍥
).
Explanation
When the resulting function is used monadically, it is the same as Atop.
(g ⍥ h) ⍵ |
g (h ⍵) |
When the resulting function is used dyadically, then it forms an Over expression (which is the true purpose of this operator).
⍺ (g ⍥ h) ⍵ |
(h ⍺) g (h ⍵) |
Examples
x←1 2 3 y←4 5 6 x +⍥(⌈/) y ⍝ add the max of x and max of y 9 ⍝ same as (⌈/x)+⌈/y 9
