<p>Joule Standard Library - N-Dimensional Arrays First-class multi-dimensional array types with compile-time rank tracking, zero-copy views, explicit broadcasting, and energy-aware operations.</p> <h2>Core Types</h2> <ul> <li><code>NDArray[T; N]</code> — Owned heap data, compile-time rank N</li> <li><code>NDView[T; N]</code> — Borrowed zero-copy view into an NDArray</li> <li><code>CowArray[T; N]</code> — Shared data with copy-on-write semantics</li> <li><code>DynArray[T]</code> — Dynamic rank determined at runtime</li> </ul> <h2>Design Principle: Explicit Broadcasting</h2> <p>Broadcasting is NEVER implicit. <code>a + b</code> requires matching shapes. Use <code>broadcast_add(a, b)</code> to make the energy cost visible.</p>
