LS-DYNA材料的二次开发-1

表示相空间相邻轨迹的平均指数发散率的数值特征。又称李雅普诺夫特征指数，是用于识别混沌运动若干数值的特征之一。(Denotes the numerical characteristics of the average exponential divergence of adjacent trajectories. Also known as the lyapunov characteristic index, is one of the characteristics used to identify some numerical values of chaotic motion.)

用于处理的地震数据加入随机噪声，可用来观看地震记录(Random noise added to seismic data)

一维到二维的转换,实现二进制的转换,并且可以实现以为到二维的转换(One dimension to the two-dimensional transformation, realize the binary conversion, and can realize thought to the 2 d transformation)

采用可变模式分解对一维时间信号进行分解，其性能优于传统EMD，LMD等方法(signal processing method)

用来读取卫星影像自带的xml文件里的各种参数(Used to read various parameters in the XML file of satellite image)

利用蒙特卡洛的方法进行威布尔参数估计，随机生成对应参数估计值，不断迭代达到需要精度(Weibull parameter estimation using Monte Carlo method.)

通过频率计数器采集到的数据可以实时计算Allan方差(The Allan variance can be calculated in real time by the data collected by the frequency counter)

模拟局部阴影下用干扰观测法实现光伏最大功率点跟踪，结果表明能较好实现最大电压的跟踪(Photovoltaic maximum power point tracking using interference observation method)

说明：  大学生综合管理系统,主要是对学生的学籍还有班级等,选课进行统一查询和管理.(students integrated management systems, mainly for the expulsion of students have classes, classes for inquiries and management.)
