Homework Statement

Hi, I'm trying to simulate an electrostatic craft going from low Earth orbit to a geostationary orbit, but I'm having some trouble with matlab. I'm not the most confident programmer at the best of times, but needs must and so I've given it a go. As far as I can tell my syntax is correct, but I can't seem to get the correct outputs. The main aim that I have is to get the program to produce a plot of the spiral orbit, but it isn't playing ball.

Basically I think I've been staring at the code for too long and can't see where I'm going wrong, so some help would be greatly appreciated.

Thanks

Homework Equations

The Attempt at a Solution

I've included the 3 files that I'm using, the main file being LEO-GEO orbit xfer

If anyone can suggest any tweaks or things that I'm missing that would be great, also, the code is supposed to ask me to input a value for the thrust, but I never seem to get a prompt - again, maybe I'm missing something here.

Thanks Again

Oh ! I'm using a computer that isn't mine and I've just realized that the files are trying to run in mathematica not MATLAB - sorry about that.

I'll have another go - sticking it into MATLAB for certain this time ! So please ignore this post for the moment

Cheers
