Convert a specified Julian Date Vector to Greenwich Mean Sidereal Time (GMST). The expected input matrix may contain multiple dimensions. The output matrix will be in the same size as the input matrix. Warning: Use caution when using GMST as a substitute for Greenwich Apparent Sidereal Time (GAST).

To run JD2GMST, use the following code sequence:
GMST = JD2GMST(JD);

Where:
JD is the Julian Date input (days)
GMST is the resulting Greenwich Mean Sidereal Time output (0 to 360deg)
