定时同步的文章，很值得看一看，算法简单，精度很高！(Timing of the article, well worth a look, a simple algorithm, high precision!)

空间谱估计music 谱估计方法,估计信号参数(Spatial spectrum estimation music spectrum estimation methods, estimates signal parameters)

IEEE 802.11ac的发送端代码，用matlab生成，包含发送端的所有模块，至RF前端(IEEE 802.11ac transmitter matlab code)

The program computes the solution to a Laplace problem by the boundary element method.

基于窗函数法的FIR数字滤波器设计与实现，程序比较简单，易懂。(FIR digital filter based on window function.)

只需修改路径，就可处理txt文件心电数据，要求此心电数据必须是R波的横坐标，可画散点图，密度图等(use the matlab to process the ECG data,detect the R-point.)

说明：  实现Brent(布伦特)优化搜索，寻找极大极小值。.M文件(brent optimize to search for the max or min data.)

substitution cipher is the method of encoding in which unit of plain text are replaced by cipher text. Monoalphabetic cipher uses a fixed message over entire message.A monoalphabetic cipher uses fixed substitution over the entire message.The monoalphabetic substitution takes a letter of an alphabet and substitutes it with another letter, this way a ciphertext is generated. The way of converting is fixed. A character of the plaintext will be replaced by the same ciphertext character, during the entire ciphertext. There is no additional key. The only way of security is to keep the substitution-table secret. A popular example for the monoalphabetic substitution is the caesar cipher.

CVX-一款在matlab中，用于解决计算包括凸优化等问题，支持线性优化和二次方优化以及半正定算法。(CVX is a modeling system for constructing and solving disciplined convex programs (DCPs). CVX supports a number of standard problem types, including linear and quadratic programs (LPs/QPs), second-order cone programs (SOCPs), and semidefinite programs (SDPs).)
