用四阶龙格-库塔法求系统在U单位阶跃输入下该系统的响应曲线(Using the four order Runge Kutta method to find the response curve )

ObjectARX开发，配电网，网络绘制，潮流计算，可靠性分析等(ObjectARX development, distribution network, network rendering, flow calculation, reliability analysis, etc.)

mfc 实现绘制3次B样条 效果很好 模块化可以在自己论文中使用(mfc achieved drawing cubic B-spline)

在AutoCAD中添加一个自定义分页侧边栏。(In AutoCAD add a custom tab sidebar.)

可以实现基本的绘图功能，画直线，矩形，圆椭圆。图形学作业(Can achieve the basic drawing functions and draw a straight line, rectangle, circle, ellipse. Graphics jobs)

说明：  通过使用dxflib库，对dxf文件进行读取(Read DXF files by using the dxflib Library)

说明：  三次B样条,程序中有部分说明,可以自由在其中进行扩展设计其它类似样条程序.(cubic B-spline, some procedures that can be carried out in one free expansion design similar kind of procedure.)

draw用法。新手必看，通俗易懂，请结合工具书(draw Xinshoubikan usage, easy to understand)

一个简单的程序，可以绘制点、线、圆、方。可以保存成一定格式的图片文件。软件最大的问题是绘图基本在对应的鼠标事件里进行，而没有在paint方法里进行，可借鉴。(A simple program, you can draw points, lines, circles, square. Can be saved into a certain format image files. The biggest problem is the graphics software basic mouse events in the corresponding conduct, but not in the paint method in the conduct, we may learn.)

5/3小波变换的提升算法实现以及对于什么叫做提升的介绍。由于5/3小波是整数小波，因此非常适合于DSP处理，且经过提升，小波变换的复杂度明显降低，将此代码的提升部分移植到DSP上，可以达到实时。(5/3 wavelet transform algorithm to enhance as well as what is to enhance the introduction. Since the 5/3 integer wavelet wavelet is therefore very suitable for DSP processing, and after upgrading, wavelet transform significantly reduced complexity, the upgrading of part of this code ported to DSP, we can achieve real-time.)
