% Computes the Earth greenwich matrix that transforms from ECI to EF.
Any input of eOfECalc will cause it to include the equation of the
equinoxes.
Type EarthRot for a demo.
--------------------------------------------------------------------------
Form:
[g, gMST, gAST] = EarthRot( T, eOfECalc )
--------------------------------------------------------------------------
------
Inputs
------
T (1,1) Julian centuries of 86400s dynamical time from j2000.0
eOfECalc (1,1) Calculate the equation of the equinoxes
-------
Outputs
-------
g (3,3) Greenwich matrix
gMST (1,1) Greenwich mean sidereal time (deg)
gAST (1,1) Greenwich apparent sidereal time (deg)
