一种（LFM）Linear frequency modulation雷达的仿真(Linear frequency modulation (LFM) radar simulation)

MATLAB不提供现成指数拟合函数，一方面由于但可以轻松通过多项式拟合转化而来，但是使用上还是不如有一个函数方便，所以特写这样一样简单实用的函数(MATLAB does not provide ready-exponential fit function, by hand because it can be easily transformed a polynomial fit, but still not as good as there is easy to use a function, it is as simple close-up of such useful functions)

一个基于粒子群优化算法源码,（PSO）的50个城市TSP问题的求解，可推广至类似NP.(A source code based on particle swarm optimization, (PSO) of the 50 cities TSP problem solving, can be extended to similar NP.)

九点差分格式，精度比五点差分要高，对于实现有限差分，是一个重要的程序(Nine-point difference scheme, the accuracy than the five-point difference is higher, for the realization of finite-difference, is an important procedure)

对常用的MATLAB程序函数进行了归纳总结，简单易查，使用方便。(MATLAB program commonly used functions are summarized, simple and easy to search, easy to use.)
