采样系统实时信号的频谱分析MATLAB程序(Real-time signal sampling spectral analysis program MATLAB)

matlab 编写的下雪程序，很适合在冬天看雪花落下过程(Matlab prepared by the snow program, it is suitable in the winter to see snow falling process)

二元傅立叶全息图在matlab上的实现。体现了其五个实现步骤。结果为生成啁啾光纤光栅。(Binary Fourier hologram on the matlab realize. Reflects the achievement of its five steps. The results for the generation of chirped fiber grating.)

线性调频信号是一种雷达常用的电磁波信号，当雷达信号检测到目标时候，反射后得到雷达回波信号，此时由于多普勒效应，信号的频率发生偏移，这个源码仿真出雷达检测到目标速度信息的回波信号。(LFM signal is a commonly used electromagnetic radar signal, when the radar signal detection to the target time, after reflection of radar echo signal, at this time due to Doppler effect, the signal)

Cholesky分解，以某个具体的矩阵进行的分解，便于求解线性方程组(Cholesky decomposition)

使用matlab编写的图像特征提取软件，可对图像进行批量处理(Written using the image feature extraction matlab software, batch processing of images)

负责火星的一个低轨道空间站的设计。为简化结构，该空间站由一系列密闭的立方体（airtight cubical modules ACM）组成，这些ACM曾连接在一起。困扰你的一个问题是致命的病菌也许留在火星的上层大气中。因为空间站有时需要在上层大气中飞行，所以急需在ACM的各个接触面进行额外的防护，无论是边对边还是面对面，连接是密闭的，所以没有细菌能够进入。一个ACM与另外一个ACM共享的面不需要防护。如果在每个ACM每个面上都加防护，花费巨大。因此，需要知道ACM额外防护的确切面数目(Responsible for the design of a low-orbit space station on Mars. In order to simplify the structure of the space station by a series of closed cubes (airtight cubical modules ACM) composed of these ACM had together. One problem is bothering you deadly germs might stay in the upper atmosphere of Mars. Because the station is sometimes necessary to fly in the upper atmosphere, so urgently needed in all contact surfaces of the ACM additional protection, either face to face or side-to-side, the connection is closed, so no bacteria can enter. An ACM ACM shared with another surface does not need protection. If you have added protection on each side of each ACM, costly. Therefore, the need to know the exact number of additional surface protection ACM)

模式识别。PCA实例，经调试可用，希望能帮到需要的人。(Pattern Recognition. PCA instance, debugging is available, I hope to help people in need.)

说明：  旅行商问题 可求解最短距离的，有距离路线图，运行次数(Summary:Each salesman travels to a unique set of cities and completes theroute by returning to the city he started from Each city is visited by exactly one salesman)
