基于贝叶斯人脸识别技术的matlab人脸识别程序，在ORL库上实现，也可换用别的库进行运算，只需要更改样本数量(Bayesian face recognition technology based on face recognition matlab program, implemented on ORL database can also be used for other library operations, only need to change the number of samples)

谱减法是一种比较简单的语音降噪的方法，在语音信号具有较高的信噪比的情况下具有良好的降噪功能。 (Spectral subtraction is a relatively simple pronunciation methods of noise in speech signal with high signal-to-noise ratio (SNR) of cases with good noise function.)

重要的模拟程序，模拟精度很高，值得大家好好参考，好好学习一下(Important simulation, the simulation accuracy is high, is worth a good reference to learn about)

说明：  利用Matlab编写求取4级移位寄存器的M序列 设初始序列为:1 1 1 1 通过一个四级的移位寄存器,其中在第三级有负反馈(一个模二加法),即将序列的第三位和第四位相加(如序列1 1 1 1经移位寄存器第一次移位后为0 1 1 1)的值再赋到第一位. 序列的周期为16.(The use of Matlab to prepare to strike four of the M shift register sequence based initial sequence as follows: 1 1 1 1 4 through a shift register, which in the third grade there is negative feedback (one-mode two adder), the upcoming series third and fourth combined (such as the sequence 1 1 1 1 by the shift register after the first shift for the 0 1 1 1) the value given to the first again. The cycle sequence was 16.)

给创新工场求职者的一封信 有兴趣的看一下(Innovative workshops to job seekers interested in a look at a letter)

自己编程的matlab成绩查询系统，能实现对.txt以及.xls等多种文件格式的读取，并通过mcc命令转化为可执行文件。压缩包内含所有源码。(Own programming matlab query system can achieve right. Reading txt and. Xls and other file formats, and through the mcc command into an executable file. Archive contains all the source code. .)

该程序用matlab写成，已包含vof（根据Hirt的方法）内容，但该部分尚不成熟。对于不包含自由面的计算比较成功。(The program written with matlab, included vof (according to Hirt' s method) content, but that part is not yet mature. For the calculation of the free surface does not contain more successful.)

libev-4.15源码 libev是Marc Lehmann用C写的高性能事件循环库。通过libev，可以灵活地把各种事件组织管理起来，如：时钟、io、信号等。libev在业界内也是广受好评，不少项目都采用它来做底层的事件循环。node.js也是其中之一(libev-4.15 source libev Marc Lehmann is written in C, a high-performance event loop library. By libev, the flexibility to manage the organization of various events, such as: clock, io, signals. libev is also widely acclaimed in the industry, many projects have adopted it as the underlying event loop. node.js is one of them)

寻找很多个点的最大包围线。通过扫描法，分成4个代码文件实现。最后附图给出前后结果。(Looking for maximum points surrounded by a lot of lines. By scanning method, divided into four code files to achieve. The results are given before and after the final drawings.)
