通过时频转换法来，来画BPSK巴克码的模糊函数，tao（时延）切面，fd（多普勒频移）切面。以及其模糊度图的画法(Through the time-frequency conversion method to draw Barker code BPSK ambiguity function, tao (delay) section, fd (Doppler shift) section. And its ambiguity diagram drawing)

最后的测试程序，得出文本检索的正确率和召回率(In the end, the cosine similarity of texts is used to measure the similarity between the query and documents. The data comparison indicates that this algorithm has well experimental results. Moreover, it gets the advantage over the classic LSA retrieval algorithm in precision and operational efficiency.)

对matlab初学者很有帮助，尤其是simulink的爱好者。(helpful to beginners Matlab, Simulink is particularly fond.)

这是Matlab初学者编写的小程序，内容简单明了，比较适合刚入门的人学习(This is a small program written in Matlab beginners, the content is simple, more suitable for people just getting started learning)

计算B样条非零基函数及其直到n阶导数（n<=p）的算法，p是B样条基函数的次数(Calculation of B-spline basis functions and until nonzero derivative of order n (n < = p) algorithm, p is the B-spline basis functions of times)

通信系统仿真中，QPSK调制下的高斯信道Matlab仿真(the simulation of the Gaussian channel in communication system )

high pass filtering in images

二维经验模式分解（BEMD）程序，可用于图像分解 (Bidimensional Empirical Mode Decomposition)

说明：  实现利用高斯分布聚类，即完成em算法，直接在matlab上运行，可以作图直观显示（二维数据）(Achieve Gaussian distribution clustering, complete em algorithm, running directly on matlab, you can visualize mapping (two-dimensional data))

说明：  newmark法解决单自由度体系振动问题(newmark method to solve the problem of a single degree of freedom vibration system)
