脉冲信号模糊函数u表示调频斜率，fig4—5和fig-6是模糊函数图形的绘制，lfm_ambg.m是模糊函数表达式(Pulse signal ambiguity function u express FM slope, fig4-5 and fig-6 is the ambiguity function of rendering graphics, lfm_ambg.m is ambiguous function expression)

this file draw the nyquist diagram of multi input- multi output systems that they are such important kind of systems in control systems

pscad 中除了自带实例外的例子,包括IEEE34，传输线路故障，变电站(pscad instance, in addition to its own outside of the examples, including IEEE34, transmission line fault, substations)

说明：  实现对单图层dxf文件的信息采集，例如直线的起止点、圆弧的圆心与半径等(Achieving Information Collection of DXF Files with single layer)

针对ANSYS开发的APDL，该命令流用于生成中国60kg钢轨，从而避免了繁琐的多曲线建模，十分方便。另外，基于该命令流，用户可以推演出更复杂的型面优化建模。(Developed for ANSYS APDL, the order flow is used to generate Chinese 60kg rails, thus avoiding the cumbersome multi-curve modeling, very convenient. In addition, based on the order flow, the user can deduce a more complex profile optimization modeling.)

单文档绘图工具，包括直线，曲线，扇形，圆形，圆角矩形，矩形等图形，还可以设置线条的颜色等属性。(Single document drawing tools including lines, curves, fan-shaped, round, rounded rectangle, rectangle and other graphics, you can also set the line color and other attributes.)

Visio 2010图形设计实战技巧精粹，让读者一目了然，更好地掌握Visio 2010。(Visio 2010 graphic design essence of combat skills, to give readers a glance, a better grasp of Visio 2010.)

本程序使用C#进行supermap二次开发，实现在工作空间里打开CAD数据，并实现图层的放大、缩小、漫游等操作。(The program uses C# for supermap secondary development of open space at work to achieve CAD data, and to achieve layers of enlargement, reduction, roaming and other operations.)

读取DXF文件(2000,2002版本),包括了分层管理数据的思想,供大家参考(read DXF files (version 2000, 2002), including a hierarchical data management thinking, for your reference)

用于求解各阶贝塞尔函数和汉克尔函数零点，希望对大家有帮助。(besselj and hankel functions)
