Implementation Notes:

• Stride Handling: The implementation correctly handles negative strides. The target index iy is calculated relative to the offset (iy = ix + (N-1)*stride), ensuring the logical view is reversed regardless of the underlying memory traversal direction.

• Type Safety: Following the pattern of existing BLAS ndarray implementations, explicit runtime type validation is omitted to prioritize performance in the inner loop. The implementation relies on TypeScript definitions and upstream ndarray constraints.
