The Legendre pseudospectral method for optimal control problems is based on Legendre polynomials. It was originally proposed by Elnagar and coworkers in 1995.[1] Since then, Ross, Fahroo and co-workers[2][3] have analysed, extended and applied the method for an impressive range of problems. An application that has received wide publicity is the use of their method for generating real time trajectories for the International Space Station.[4]
