Equinoxes and Solstices
EQNSOL computes the date of equinoxes and solstices for the input year. This is based upon the formulas given by Jean Meeus in his "Astronomical Algorithms". The date is computed in Julian Date. This function take in JD2CAL function of "Geodetic Toolbox" by Mike Craymer (ID:15285) to convert Julian Date into gregorian calendar date.
Syntax: Y=EQNSOL(YEAR,VERBOSE)
Inputs:
YEAR (default=current Year).
VERBOSE (default=1)
Outputs:
- Y=datenum formatted array.
EQ=EQNSOL(...) will stores dates in Matlab format
Example:
y=eqnsol(2007)
All dates and times are referred to GMT without DST
