tidemVuf: Nodal Modulation Calculations for Tidem

Description

Do nodal modulation calculations for tidem. This function is based directly on t_vuf in the T_TIDE Matlab package [1].

Usage

tidemVuf(t, j, latitude = NULL)

Arguments

t

The time in POSIXct format. (It is very important to use tz="GMT" in constructing t.)

j

Indices of tidal constituents to use.

latitude

Optional numerical value containing the latitude in degrees North.

Value

A list containing items named v, u and f (see the T_TIDE documentation).
