coriolisfdocumentation
Thecoriolisffunction returns the Coriolis frequency for any given latitude(s). The Coriolis frequency is sometimes called the Coriolis parameter or the Coriolis coefficient.

Syntax
f = coriolisf(lat) f = coriolisf(lat,rot)
Description
f = coriolisf(lat)返回地球的科里奥利frequency for any locations(s) at latitude(s)lat. By default, the Coriolis frequency is given in units of rad/s.
f = coriolisf(lat,rot)specifies a rate of rotationrot. By default,rotis Earth's present-day rate of rotation 7.2921 x 10^-5 rad/s, but a different rate may be specified to model Earth at a different time, other celestial bodies, or the Coriolis parameter in a different unit of frequency.
Example
Make a a 1°x1° grid, withcdtgrid, and get the Coriolis parameter for corresponding to each grid cell:
[Lat,Lon] = cdtgrid; f = coriolisf(Lat);
