Hi, I'm running a long simulation of the Juno space probe that has about
4,000,000 iterations, the computer is a DELL laptop running Windows XP, and
I get different trajectories using MATLAB and Octave. The math used is the
4 basic operations plus squaring with the exponent operator and the sqrt
function. The differences occur after 5 significant digits and two million
iterations, then the physics takes over and the trajectories diverge
significantly. I cut and pasted the program from MATLAB to Octave without
and changes necessary.
Is there any explanation for this?
