Picard-Chebyshev Method

Demo function used to demonstrate how to use the Picard-Chebyshev method This will propagate an orbit a total of one period and compare the solution to the analytical solution using kepler universal variable propagation.

This is a migration the original code (MatLab) to C

C

Compile with:

gcc main.c src/kepleruniversal.c src/kepleruniversal.h src/picardchebyshevdemo.c src/picardchebyshevdemo.h src/vmpcm.c src/vmpcm.h src/matlab.c src/matlab.h
