This function gives the parameters for about 40 main wave components of Earth tides due to Sun and Moon, using the harmonic development of Arthur Thomas Doodson. For a given wave, it returns in a structure the 6 Doodson's arguments, wave Darwin's symbol, wave description and the wave period (in days).

>> X=doodson('M2')
X =

symbol: {'M2'}
name: {'Principal lunar semidiurnal'}
doodson: [2 0 0 0 0 0]
period: 0.5175

Type doodson without argument to see the list of available waves.
