说明：  匹配追踪算法的matlab工具箱，可以比较方便的进行mp分解，效率较高，但目前的版本对于谐波原子的分解还有些问题(Matching pursuit algorithm matlab toolbox, can be more convenient mp decomposition, efficient, but the current version of the harmonic decomposition of the atom has some problems)

MATLAB CODE FOR ARITHMETIC AND LOGICAL OPERATIONS IN IMAGE

说明：  matlab 功能强大 网上下载 据说是单片机和matlab串口通信(matlab download is said to be a powerful microcontroller and serial communication matlab)

（7，4）系统循环码编码器 code_out = cyclic_coder(code_in) 该系统循环码编码器的生成多项式是g(x) = x^3 + x + 1 输入参数code_in是信息码字，是1×4的行向量；输出code_out是编码后的系统 循环码字，是1×7的行向量。 函数运行时，同时画出输入信息码字和循环码字的波形图。( (7,4) cyclic code system Encoder code_out = cyclic_coder (code_in) cyclic code encoder of the system generating polynomial is g (x) = x ^ 3+ x+ 1 of information input parameters code_in code word is 1 × 4 row vector output code_out System is encoded codeword cycle, the row is 1 × 7 vector. Function to run at the same time draw the input code word and code word cycle waveform.)

simulation bad three level

说明：  信号处理中的加窗程序，可以加汉宁窗等窗函数(Windowed signal processing program, you can Hanning window function windows, etc.)

计算SQUIRT 模型，弹性波在饱和多孔介质中传播时，一种微观流动机制(used to realize the Squirt flow model)

自编滤波函数与MATLAB系统自带滤波函数对高斯噪声处理效果的比较，包括均值滤波、中值滤波等滤波函数。(Self MATLAB filter function and the system comes with Gaussian noise filtering function to compare the treatment effect, including mean filtering, median filtering and other filtering functions.)

该文件是用相位差校正技术来检测简谐波，其运行环境是在matlab中( FFT)

对NRZ.DPSK信号用matlab进行性能仿真和实现，大家可参考下(simulate and realize NRZ. DPSK signal with matlab, you can reference)
