说明：  本程序运用PMX和SWAP算子实现了TSP问题的MATLAB编程，希望大家能够用到。(The use of this program and the SWAP operator PMX achieved MATLAB programming TSP problem, hope that we can use.)

说明：  用matlab计算二维光子晶体带隙并做出带隙图 以及计算二维声子晶体（XY模）的能隙并作出图(2D Photonic crystal band structure 2D phonic crystal(XY model) band structure)

一个单位负反馈系统的滞后超前频域法校正，可直接在matlab中打开和运行(A unit negative feedback system lag correction ahead frequency domain method can directly open and run in matlab)

插值法是利用函数在某区间中若干点的函数值，作出适当的特定函数，在这些点上取已知值。此代码是牛顿插值法的matlab实现。(Interpolation function is a function of the value of the use of a number of points in a certain range, and make appropriate specific function, taking the known values at these points. This code is Newton interpolation matlab implementation.)
