说明：  ce code est écrit en matlab

可以对任何数组进行概率计算，在求数组信息熵时使用(array can be of any probability calculations, an array of information for the use of entropy)

EMD(经验模态分解)完整程序，并用于了发动机振动信号中分析，效果很好(EMD (EMD) complete the program, and for the engine vibration signal analysis, the effect is very good)

IEEE六节点无功优化算法的matlab程序，以整个系统有功网损作为优化目标，通过改变节点注入无功以及变压器变比来求解所对应的有功网损，从而达到优化目标(IEEE six-node reactive power optimization algorithm matlab program, active power loss to the entire system as the optimization objectives, as well as injecting reactive power transformer to solve than the corresponding active power loss by changing the node, so as to optimize target)

关于BCH通道下生成标准矩阵以及编码解码过程的文章(this article is concerned to standard array generation and encoding and decoding under BCH channel.)

说明：  计算金属球体RCS的MATLAB程序. 就是教科书上金属球体RCS曲线计算的MATLAB程序.(RCS calculation of the metal sphere of MATLAB procedures. Is textbook metal sphere RCS curve calculated MATLAB program.)

curve fitting program

一组取值为+/-1的随机序列，每两个数据之间插入3个0，然后将序列通过一个设计好的根升余弦滤波器，并用周期图法和Welch法分别绘制信号的功率谱。再次通过根升余弦滤波器后用stem函数绘图。(A set of values ​ ​ is+ /-1 random sequence inserted between every two data 3 0, then the sequence through a root raised cosine filter designed, periodogram and Welch method to draw the signal powerspectrum. Stem function by root raised cosine filter with drawing again.)

prints the current YMDHMS date as a timestamp

16QAM调制与解调，可以实现不同信道噪声下的误码率计算，并画出频谱和星座图(16QAM modulation and demodulation error rate calculated under different channel noise and draw the spectrum and constellation)
