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
