hi,
in the result of "]help" I can see:
λ { ... } result
⍺ { ... } left value argument
⍵ { ... } right value argument
χ { ... } axis argument
⍶ { ... } left function argument
⍹ { ... } right function argument
can someone explain to me the usage of ⍶ and ⍹
with some examples ?
I understant the first four, but not the last two.
