FrequencyEstimation

3维的FDTD的matlab实现，无毛刺，mur差分法。pml。(3-dimensional FDTD)

给出了理想光具组系统矩阵的MATLAB计算程序，并借助MATLAB进行光线追迹与数值拟合，得到了像差(球差)的多项式及曲线图．(Elastic viscoelastic correspondence principle is a method which is used to solve viscoelastic problems with elastic results using inverse Laplace transformation．The principle can combine elastic and viscoelastic me— chanies together．Therefore traditional mechanics of materials is qreatly enriched because of introducing the new materials and new theory．)

自写的基于MUSIC的ISM宽带测角谱估计算法，线性调频信号，4阵元，2目标，正常运行。(My own MUSIC based ISM broadband DOA estimation algorithm. Chirp signals, four elements, two objection. Functioning properly.)

bat algorithm for optimization
