Gravity-perturbed Earth Orbit Lambert Problem - OTB/fsolve

OTB/fsolve version of the lambert4.m MATLAB script which solves the gravity-perturbed Lambert problem

PDF document and MATLAB script that demonstrates how to solve the Earth orbit, J2-perturbed form of Lambert’s problem using fsolve from the MATLAB Optimization Toolbox. Lambert’s problem is concerned with the determination of an orbit that passes between two positions within a specified time-of-flight. This classic astrodynamic problem is also known as the orbital two-point boundary value problem (TPBVP) or the flyby and rendezvous problems.
