bashWhich axis should a 1‑D array align to when broadcasting against a 2‑D array in APL?
Goal Determine the axis alignment of a 1‑D operand when combined with a 2‑D operand under APL broadcasting semantics. Constraints The language specification promotes the right‑hand operand’s shape to the left‑hand operand’s shape, but does not specify the axis for a 1‑D/2‑D combination. Dialects diverge: Dyalog aligns on the last axis, treating the vector as
