电力系统IEEE30节点的节点阻抗矩阵的形成程序，采用的是支路追加法(Power system IEEE30 node node impedance matrix formation program, using the branch addition method)

针对频率周期振荡的振动系统讨论自适应控制问题,在频率跟踪的基础上对频率变化的振动响应进行控 制,给出相应的估计、滤波与控制方法。首先在子空间辨识原理的基础上,通过测量信号自相关序列的递推运算获得信号 频率 然后根据估计频率实时调整带通滤波器的中心频率,使其跟踪信号频率,实现信号分量的跟踪滤波 最后在LMS方 法的基础上构造对信号分量进行控制的自适应控制器。(The adaptive vibration control of systems excited by forces of periodically varying frequencieswas dis- cussed. The presented adaptive controlwas realized on the basis of tracking of time-varying frequencies and amethod for online frequency estimation, filtering and controlwas proposed. Based on the principle of subspace identification, the time-varying frequencieswere estimated from the recursively computed autocorrelation ofmeasured signals. )

处理lasso regression。 使用stochastic Markov property。(Algorithm for solving the Lasso problem: 0.5* (y- X*beta) *(y- X*beta)+ lambda* ||beta||_1 where ||beta||_1 is the L_1 norm i.e., ||beta||_1 = sum(abs( beta )) We use the method proposed by Fu et. al based on single co-ordinate descent. For more details see GP s notes or the following paper: Penalized Regressions: The Bridge Versus the Lasso Wenjiang J. FU, Journal of Computational and Graphical Statistics, Volume 7, Number 3, Pages 397?416, 1998 )

Parse the device s DT node for an endianness specification.

此程序可以产生golden序列，只要输入相应的特征多项式，就可以得到序列(This program can produce the golden sequence, as long as the input of the corresponding characteristic polynomial, you can get the sequence)

this code use for matlab

说明：  matlab m语言编写的拼图游戏，对于学习matlab很有帮助(matlab m jigsaw puzzle languages, matlab helpful for learning)

matlab simulation for TL and cable

This Matlab code shows how to perform edge detection by Sobel method in horizontal & vertical direction and the effect of increasing and decreasing the threshold value . Besides, you can try to perform the edge detection by other method in the same ways such as Prewitt , Roberts , Canny and others.
