The JPL planetary ephemerides are saved as files of Chebyshev polynomials fit to the Cartesian positions and velocities of the planets, Sun, and Moon, typically in 32-day intervals. The positions are integrated in astronomical units (au), but with polynomials stored in units of kilometers.

I am currently trying to run JPL_Eph_DE405.m and it keeps giving me the error that index exceeds matrix dimensions, the global variable PC is a 0x0 double... any suggestions?
