国外高手写的可以读写dxf格式信息。值得收藏(Foreign experts to write the information can be read dxf format. Worth collecting)

利用matlab绘制Rotman透镜，并用简单的随机搜索进行性能优化，优化部分算法比较简单，可自行改用更有效的算法(Design Rotman Lens with matlab)

已知型值点反求控制点，最后获得B样条曲线(Data points are known to reverse the control point, and finally obtain B-spline curve)

说明：  使用matlab代码画语音信号的语谱图，可作为参考资料(Using matlab code to draw speech signal spectrogram can be used as reference.)

图形学画图,直线,圆,多边形,曲线,随手画,文本,裁剪(Graphics drawing straight lines, circles, polygons, curves, hand painting, text, cutting)

netcdf的可视化工具包，对于直接读取netcdf数据非常便利(netcdf visualization toolkit, for direct reading netcdf data is very convenient)

自由曲线图表、柱状图、饼图的实现与转换，基于一套简单的图形类库（源代码在内）。(free curve charts, column, pie and the realization of conversion, based on a simple set of graphics libraries (including source code).)

S形速度控制曲线较之梯形曲线能够带来更小的负载速度超调与调整时间。(failed to translate)
