matlab处理信号处理的程序，简单但很有参考价值(matlab procedures to deal with signal processing, simple but useful reference)

按照给定指标采用模拟低通滤波器（巴特沃思低通）去逼近理想模拟低通滤波器 ，然后通过双线性变换法对模拟滤波器进行数字化，得到数字滤波器 。(Indicators in accordance with a given analog low-pass filter (Butterworth low-pass) to approximate the ideal analog low-pass filter, and then through the bilinear transformation method of digitizing analog filters, the digital filter.)

it is an implementation of the algorhytm for the identification R peaks based on Pan-Tompkin

User Activity Monitoring program in POS Application.

create a new Boolean object whose default value is the value of the boolean.

通过单边选择实现低复杂度的置信传播（BP）算法，并将此算法应用于检查模型中，可有效提高系统的性能，且具有较低的复杂度(Select achieved through unilateral low-complexity belief propagation (BP) algorithm, and the algorithm is applied to check the model can effectively improve system performance, and has lower complexity)

设计一程序，要求用带缓存的流文件I/O操作，在“./tmp”目录下,打开名称为“tmpfile”的文件。如果该文件不存在，则创建此文件；如果存在，将文件清空后关闭。W或w+(design a program, it need to use the cache files to operate the in/out directory)

说明：  应用最小熵解卷积对滚动轴承进行故障诊断，列子及仿真(bearing fault diagnosis)

UNIX网络编程第2卷 进程间通信。学习Linux很好的书籍(UNIX Network Programming Volume 2 Interprocess communication. Good books to learn Linux)

本文对传统方法与MATLAB编程方法进行了比较，研究了用MATLAB实现巴特沃斯滤波器的设计，只要改变程序中相应 的参数可以很容易地实现低通、高通、带通、带阻滤波器，简化了模拟滤波器的设计。(Filter Design using matlab )
