说明：  b样条曲线程序和gui界面，输入参数画出曲线(B-spline curve program and GUI interface, input parameters to draw the curve)

初学者常用的matlab绘图代码及讲解课件(Matlab drawing codes and instructional courseware commonly used by beginners)

对于刚接触曲线拟合C++编程的同行是一个不错的例子。(刚接触curve fitting for the C++ Peer programming is a good example.)

自己利用PSCAD搭建的２种PPL锁相环，能够自己调节ＰＩ参数，并与自带的ＰＬＬ进行了测试比较。(PSCAD build their own use two kinds of PPL phase-locked loop to adjust the PI parameters of their own, and with the built-in PLL more)

集中介绍了HDC,CDC,CClientDC,CPaintDC,CWindowDC的使用方法和区别，绘图显示效果，区分窗口客户区。(Focus on the HDC, CDC, CClientDC, CPaintDC, CWindowDC to use and distinction, graphics effects, to distinguish the window client area.)

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)

AUTO CAD 2013破解程序，非常好用，使用多次均能成功。(AUTO CAD 2013 crack program)

经典绘图（见word文档）：三维曲线，一窗口多图形，图形样式、标注、题字，绘制心形图，用双轴对数，绘制数据向量，条形图，水平条形图，绘制矩阵的面积图，二维饼图，误差图，绘制火柴杆图，绘制羽列图，绘制8阶魔方矩阵的等值线图和阶梯图，绘制玫瑰花图，罗盘图，梯度场矢量图，三维网格图，绘制高斯分布函数的网格图，曲面图，绘制曲线图，三维饼图。三维条形图，绘制柱形图，三维瀑布图，等高线，绘制一个球面，三角形表面图，三维动画图。将word代码拷贝到m文件即可运行，word文件中还有做好的图样例。(The classical drawing (see word document): 3D curve, a window graphics, graphic style, annotation, inscriptions, draw a heart, with double logarithm, drawing data vector, bars, horizontal bar charts, area mapping matrix, two pie charts, error map, drawing fire wood bar graph, plotting feather diagram, isoline chart and the ladder chart of 8 order magic square matrix, drawing compass rose diagram, diagram, gradient vector, three-dimensional grid map, drawing Gauss distribution function of the grid map, the surface chart, draw curve, the 3-D pie chart. A 3-D bar chart, draw a column chart, 3D waterfall map, contour, draw a spherical, triangular surface map, 3D animation graph. Copy the word code to the m file to run, and to map sample word file.)

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：  问题的提出：根据“心”形曲线的数学参数方程，绘制曲线并输出屏幕。在各坐标点处循环显示“LOVE”的各字母。 编程思路：“心”形曲线的数学参数方程为: (Of the problem: According to the &quot heart&quot -shaped mathematical curve parameter equation, drawing curves and output screen. Coordinates of points in the cycle show &quot LOVE&quot in the letter. Programming idea: &quot heart&quot -shaped mathematical curve parameter equation:)
