edge linking algorithm

说明：  图片隐写算法实现，采用python代码实现。(Picture steganography.)

说明：  通过聚类实现信号分选、采用脉冲重复间隔的方法。(Signal sorting by clustering the method of pulse repetition interval is adopted.)

非常方便的滤波器设计软件，能方便的设计出多种滤波器。-Very convenient for filter design software, to facilitate the design of a variety of filters.

用来实现abaqusGUI操作脚本化的一个实时动态小程序(A real-time dynamic applet for abaqusGUI operation scripting)

一个精简典型的的建模实例，进行了建模、加载和静力分析等基本步骤(A streamlined and typical modeling example with basic steps such as modeling, loading, and static analysis)

牛顿－拉夫逊法潮流计算 基本步骤： 　　（1）形成节点导纳矩阵 　　（2）将各节点电压设初值U， 　　（3）将节点初值代入相关求式，求出修正方程式的常数项向量 　　（4）将节点电压初值代入求式，求出雅可比矩阵元素 　　（5）求解修正方程，求修正向量 　　（6）求取节点电压的新值 　　（7）检查是否收敛，如不收敛，则以各节点电压的新值作为初值自第3步重新开始进行狭义次迭代，否则转入下一步 　　（8）计算支路功率分布，PV节点无功功率和平衡节点柱入功率。(Newton-Raphson method flow calculation basic steps : (1) formation of nodal admittance matrix (2) to set up the initial node voltage U, (3) the initial node-generation-related demand. calculated that the constant term formula Vector (4) nodes will be incorporated into the initial voltage-seeking, calculated Jacobian matrix elements (5) solving that equation, seek to amend the vector (6) to strike a new node voltage value (7) to check whether convergence, if not restrained. concentrated in the nodes of the new voltage as the initial value since the first three steps to re-start the narrow iterations. Otherwise, turn into the next (8) Calculation branch power distribution, PV nodes reactive power and balance-node into power.)

ESRI SHAPE文件读/写源代码。SHAPE是GIS中的重要文件格式，本代码对于研究SHAPE文件格式，实现独立代码读/写SHAPE而言，将非常轻松。建议首先阅读SHAPE文件格式白皮书。-ESRI SHAPE document read/write source code. SHAPE is a major GIS file format, the code for research SHAPE file format, achieve independent code reading/writing SHAPE, will be very relaxed. SHAPE proposal was first read the White Paper document format.
