## USAGE:

    f = gsw_f(lat)

## DESCRIPTION:

    Calculates the Coriolis parameter (f) defined by:
         f = 2*omega*sin(lat)
    where,
         omega = 7.292115e-5   (Groten, 2004)                  [ radians/s ]

    Coriolis parameter.

## INPUT:

    lat  =  latitude in decimal degrees north                [ -90 ... +90 ]

## OUTPUT:

    f    =  Coriolis parameter                                 [ radians/s ]

## EXAMPLE:

    lat = [ -90; -60; -30; 0;]

    f = gsw_f(lat)

    f =

    1.0e-003 *

      -0.145842300000000
      -0.126303136746351
