This code uses conjugate gradient method to solve the linear systemAx= b, where A is symmetric and banded. A is first stored in acompactstorage mode, using the function "compactstorage", and thenconjugate gradient method is applied to the compactly stored matrix.Input: A, initial guess x, vector...

Phi = keplerSTM(x0,dt,mu) will return the state transition matrix Phi for a set of objects described by initial positions and velocities (x0) with gravitational parameters mu, propogated along Keplerian orbits for time dt. The positions and velocities at time dt is then given by Phi*x0. x0 must...
