Atom - œi - Multidimensional Index Of

Characters: œ , i

Tags: miscellaneous , array , number

Arity: dyadic

This atom is dyadic, which means it takes two arguments.


Find the first multidimensional index of y in list x, or [] if the element is not present.


Unlike i (Index Of), this errors if the left argument is not a list rather than automatically casting to a singleton list.
