用四阶龙格库塔法和自适应变步长法求解偏微分方程组 matlab

Datcom软件的GUI版，有界面 比普通的Dos操作要方便的多。用于计算气动数据！(Datcom the GUI version of the software, there are interface than the normal operation of the convenience of multi-Dos. Used to calculate the aerodynamic data!)

说明：  Introduction In this blog, we examine the issue of identifying unit roots in the presence of structural breaks. We will use the quarterly US current account to GDP ratio to compare results from a number of unit root test.

该程序实现的是种子生命的模拟，生存：有两个或三个邻居的种子将存活到下一代，即仍然占据该格子； 死亡：如果有四个或更多的邻居，种子将因为过度拥挤而死亡；如果种子只有一个或零个邻居，将因为孤独而死亡； 繁殖：如果一个空格子有三个邻居，那么将会长出一粒新种子。一种模式在经过若干代之后有以下四种可能的结局之一： 消亡； 不变――静态； 振荡――在一组模式间循环多次后在相同的位置出现相同的模式； 滑动――在一组模式间循环多次后在不同的位置出现相同的模式。该程序允许用户指定初始的模式或计算机自动创建初始的模式； 显示进化的过程，即历代模式； 当模式消亡就停止进化，或者提示用户是否继续显示下一代，或开始新的案例，抑或退出。 -The program implementation is the seed of life simulation, survival: There are two or three neighbors of the seed will survive to the next generation, that is still occupying the lattice Death: If there are four or more neighbors, the seeds will die because of overcrowding if seed is only one or zero neighbors, will die because of loneliness Breeding: If a sub-space has three neighbors, then it will grow a new seed. After a pattern after several generations have the following one of four possible outcomes: Die Constant- static Oscillation- a group of modes in the loop on many occasions in the same location after the same pattern emerged Sli

vc调试模式下运行程序常用的动态库,希望给一些朋友帮助,特收集起来共享.(vc debug mode used to run programs under the dynamic library, hoping to help give some of my friends, to share special collected.)

实现三相逆变器的闭环控制，基于电感电流和电容电流。实现逆变器的双闭环控制，动态性能良好，通过坐标转化为DQ坐标轴使得追踪精度良好，这里只提供了主函数部分，包括坐标变换，PI计算，相关的外设初始化，需要自己配置。(Realizes closed-loop control of three-phase inverters based on inductor current and capacitor current. Inverter dual-loop control, dynamic performance is good, through the coordinates of the DQ axis to make the tracking accuracy is good, here only the main part of the function, including the coordinate transformation, PI calculations, related peripheral initialization, you need to configure.)
