Amt

Amt is the negative-frequency coefficient array evaluated at the current transform time:

Description

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

Amt is the negative-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 Am, t, t0, and modal frequency without changing Am.
