ieee 的标准文献，学习ldpc码很有帮助的，可以参考参考，老外的东西还是比较权威的(ieee standard documents, helpful learning ldpc code, can refer to the reference, what foreigner, or more authoritative)

一个有关人脸识别的程序，是PCA和SVM的，可以运行(a code about face recognition)

wolf-powell算法,运行在MATLAB环境中，用于搜索步长的计算(wolf powell algorithm)

CLPF 理想低通滤波ICHPF 理想高通滤波 的实现用于图像的处理(CLPF ideal low-pass filter ICHPF ideal realization of high-pass filtering for image processing)

设计的软件锁相环的例子，自己写的，根据原理编的(PLL design example of software that he wrote, according to the principle for the)

该程序实现多特征自适应阈值算法，两个matlab文件，一个为函数，该函数求出信号的特征量值并通过梯度下降法训练出其初始阈值，另一个为主函数，调用该函数文件；该程序将4路信号，每一路信号的特征量值及其自适应阈值求出来，并一起画出图来。(The program features multi-adaptive threshold algorithm, two matlab files, one for the function,the function seek out characteristics value and initial threshold value of the signal by gradient descent , the other main function, called the function file the program seek out four signals , characteristics of each road and the adaptive threshold value,then draw them together on the map.)

this file is gretz simulink in matlab software

该仿真程序以倒立摆数学模型为例，用于求系统传递函数、传递函数的极点以及开环脉冲响应。(The simulation program pendulum mathematical model, for example, is used the demand system transfer function, the transfer function poles as well as the open-loop impulse response.)

说明：  有关自动控制方面的一阶微分响应，matlab仿真程序(control of the first order differential response Matlab simulation program)

该程序为matlab代码。通过对相同数据分别进行DFT与FFT这两种变换，来对比两者的异同。(The program for the matlab code. By the same data were carried out both DFT and FFT transform, to compare the similarities and differences between the two.)
