    Declaration

    Swift

    @inlinable
public func closestEntryIndex(toOutput output: Output) -> Int?

  • Looks up the indices on table that approximate the given producer function towards zero, and returns the indices of the inputs that maximally approached zero.

    Returns an empty array if this lookup table is empty.

    Expects producer to be a contiguous function mapping Input into Output.Scalar.
