Apt

Apt is the positive-frequency coefficient array evaluated at the current transform time:

---

Description

Complex valued property with dimensions \((j,kl)\) and units of \(\mathrm{m\,s^{-1}}\).

Discussion

Apt is the positive-frequency coefficient array evaluated at the current transform time:

\[A_+^{k\ell j}(t) = A_+^{k\ell j}(t_0) e^{i\omega^{k\ell j}(t-t_0)}.\]

It is computed from the stored Ap, t, t0, and modal frequency without changing Ap.
