They compare the extracted <code>+\\omega</code> content of the FDTD run directly against the FDFD solution and are the main accuracy benchmarks in the test suite.</p> <p><code>examples/waveguide_real.py</code> answers a different, stricter question: how well a late raw real snapshot matches <code>Re(E_\\omega e^{i\\omega t})</code> on a monitor plane. That diagnostic is useful, but it also includes orthogonal residual structure that the phasor comparison intentionally filters out.</p> <p>The API pages are better read as a toolbox map and derivation reference:</p> <ul> <li>Use the FDTD API for time-domain stepping, CPML, phasor extraction, and real-field reconstruction from FDFD phasors.</li> <li>Use the FDFD API for driven frequency-domain solves and sparse operator algebra.</li> <li>Use the Waveguide API for mode solving, port sources, and overlap windows.</li> <li>Use the fdmath API for the lower-level finite-difference operators and the shared discrete derivations underneath both solvers.</li> </ul>"},{"location":"#build-outputs","title":"Build outputs","text":"<p>The docs build generates two HTML views from the same source:</p> <ul> <li>a normal multi-page site</li> <li>a print-oriented combined page under <code>site/print_page/</code></li> </ul> <p>If <code>htmlark</code> is installed, <code>./make_docs.sh</code> also writes a fully inlined <code>site/standalone.html</code>.</p>"},{"location":"api/","title":"API Overview","text":"<p>The package is documented directly from its docstrings.
