Finite_Difference_Beam_Propagation_Method

产生随机信号观测样本，不同信噪比和归一化频率。利用基于FFT的自相关函数快速计算方法估计其自相关函数。(Generate random signal observation samples, different signal to noise ratio and normalized frequency.Based on FFT calculation method of the autocorrelation function to quickly estimate the autocorrelation function.)

dfig simulation is explained with the help of matlab

assingment problem With this package, I provide some MATLAB-functions regarding the rectangular assignment problem. This problem appears for example in tracking applications, where one has M existing tracks and N new measurements. For each possible assignment, a cost or distance is computed. All cost values form a matrix, where the row index corresponds to the tracks and the column index corresponds to the measurements. The provided functions return an optimal or suboptimal assignment - in the sense of minimum overall costs - for the given matrix.
