11 May 2013 Low-Thrust Orbital Transfer with Solar-Electric Propulsion orbital transfer using solar-electric propulsion Author: David Eagle Waldren, Janice

I'm confused about how to use the output data to create a polar plot of the radius vs true anomaly so that the spiral transfer can be visualized.
30 Mar 2013 Optimal Impulsive Orbital Transfer MATLAB script for the solution of the one and two impulse orbit transfer between two Earth orbits. Author: David Eagle Gonzalez, Julio

“Numerical Investigation of Minimum Impulse Orbital Transfer”, AIAA Journal, 3, 2328-2334 (1965);

This is the correct citation.
12 Jan 2013 Optimal Impulsive Orbital Transfer MATLAB script for the solution of the one and two impulse orbit transfer between two Earth orbits. Author: David Eagle Darren

Yes. Hohmann only describes a transfer between two coplaner circular orbits. This specifically solves the more general problem of minimizing the delta-v between orbits with eccentricities less than 1 (general elliptical problem that includes circular) that might have an inclination difference between them or even be on a different ascending node. The minimum solution will split inclination change in between the two burns.

28 Nov 2012 Optimal Impulsive Orbital Transfer MATLAB script for the solution of the one and two impulse orbit transfer between two Earth orbits. Author: David Eagle C.J. Harris

Are there any benefits to this over a simple Hohmann orbital transfer?
