wavespectra.core.npstats.dpm(ipeak, momsin, momcos)

Mean direction at the peak wave period Dpm.

Args:

• ipeak (int): Index of the maximum energy density in the frequency spectrum E(f).

• momsin (1darray): Sin component of the 1st directional moment.

• momcos (1darray): Cos component of the 1st directional moment.

Returns:

• dpm (float): Mean direction at the frequency peak of the spectrum.
