Code to run the Non-negative Matrix Factorization algorithm as presented in the Lee, Seung 1999 Nature paper.

说明：  首先，在非视距环境中，信号传播将产生多径效应，这将导致对到达时间的错误估计。其次PSO(Firstly, in NLOS environment, signal propagation will produce multipath effect, which will lead to wrong estimation of arrival time. Second, PSO)

SIFT ALGORITHM IS BEST OPTION

Control vector parameterization, also known as direct sequential method, is one of the direct optimization methods for solving optimal control problems. The basic idea of direct optimization methods is to discretize the control problem, and then apply nonlinear programming (NLP) techniques to the resulting finite-dimensional optimization problem.
