说明：  海森频率格纸的绘制、绘制P-III频率曲线(Drawing P-III frequency curve with Hessian frequency grid paper)

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

基于PACAD4.2搭建的双有源桥DC-DC变换器仿真模型，可实现基本的功能，可快速入门并可在此基础上进行进一步的学习等。(PACAD4.2 built based on the dual active bridge DC-DC converter simulation model, the basic functions can be achieved, can be quickly started, and on this basis for further study.)

2个基于pscad的微型燃气轮机模型，适合模型仿真的人使用(2 pscad microturbine-based model for people to use simulation models)

对lidar数据进行处理，并建立delaunay三角网(On lidar data processing, and the establishment of delaunay triangulation)

等值线函数.// As this code is ported from FORTRAN-77, please be very careful of the // various indices like ilb,iub,jlb and jub, remeber that C/C++ indices // starts from zero (0)(contour function.// As this code is ported from FORTRAN-77, please be very careful of the// various indices like ilb, iub, and* address, remember that the C/C indices// starts from zero (0))

图形学上机程序，利用种子填充和扫描线算法实验区域的填充。有助于学习者掌握填充算法。进一步理解和学习图形学。(Graphics on procedures, the use of seed filling and scan line algorithm experimental area fill. Help learners fill algorithm. Further understanding and learning graphics.)

本代码实现两段贝切尔曲线的拼接，这里会分别显示两段曲线，再显示拼接后的曲线。(The code implements the splicing of the two sections Bei Qieer curve, and here are two curves, and then display the mosaic curve.)

零阶一类贝塞尔函数曲线，并画出其包络线的源程序(Zero-order Bessel function curve and draw the envelope of the source)

改进的Bresenham算法，用visual c++ 实现(Improved Bresenham algorithm, using visual c++ achieve)
