根据公汽线路信息数据，编写对任意车站，寻找通过该站的汽车线路的M文件； （3）编写M文件，对任意两个车站m,n，判断是否有线路通过这两车站，若有则编写寻找通过该站的汽车线路的M文件 （4）对任意两个车站m,n，若没有线路直接通过这两车站，编写通过一次转车而到达两站的M文件 (According to the bus line information and data to write on any station to find the M-file line through the station car (3) the preparation of the M-file, any two stations m, n, determine whether the line through these two stations, if write to find the M-file line through the station car (4) any two stations m, n, if there is no line directly through the two stations, the preparation time to change trains to reach the M-file of the two stations)

There are 3 models of Buck converter closed loops with PWM done in simulink and they work properly

整数规划：用割平面法求解整数规划 用分支定界法求解整数规划 用枚举法（包括穷举法和隐枚举法）求解0－1规划 (Integer programming: cutting plane method for solving integer programming with branch and bound method for solving integer programming Solving 0-1 planning enumeration method (exhaustive method and implicit enumeration))

GUI设计蜘蛛爬行，针对互相追逐的蜘蛛，建立他们的爬行轨迹，同事，计算相遇时间等的Matlab程序文件。(GUI design spider, spider chasing each other, build their crawling track, colleagues calculated to meet the time of the Matlab program file.)

cohere(x,y,M) computes the coherence function using successive DFTs of length with a Hanning window and 50 overlap. (The window and overlap can be controlled via additional optional arguments.) We see a coherence peak at frequency cycles/sample, as expected, but there are also two rather large coherence samples on either side of the main peak. These are expected as well, since the true cross-spectrum for this case is a critically sampled Hanning window transform. (A window transform is critically sampled whenever the window length equals the DFT length.)

遗传算法Matlab源代码,优化目标函数比较广泛，是常用的算法之一，同时也是学习其他算法的基础。(Genetic algorithm (ga) )

实现了chirp信号的分数阶傅立叶变换，表现出了其能量聚集效果，另外对单频、多频、高斯信号进行了分数阶傅立叶变换(The chirp signal Fractional Fourier Transform, showing the effect of its energy gathered addition of single-frequency, multi-frequency Gaussian signal Fractional Fourier Transform)

针对传统粒子群算法初期收敛较快，而在后期容易陷入早熟、局部最优的特点，提出了一种新的混沌粒子群优化算法(For early traditional PSO algorithm converges faster and easier in the late fall early, optimal local characteristics, we propose a new chaotic particle swarm optimization)

matlab源程序 有点小错误但是稍微改下就可以了 人工免疫用于故障诊断源程序(matlab source code to change a little wrong, but under it a little artificial immune source for troubleshooting)
