实用三百例 前后学习 融会贯通 而且每个实例都是一个小模块 从画图到计算(Around three hundred cases of practical mastery learning and each instance is a small module from the drawing to the calculation)

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:)

测量弧的线性长度并在绘图平面标注弧长。arcdim(The linear length measuring arc and arc length dimension in the drawing plane. arcdim)

实现了DDA直线生成算法画直线，Bresenham圆弧生成算法画圆弧(Achieve DDA line drawing algorithm to generate a straight line, Bresenham algorithm for drawing arcs arc generated)

pscad做的整流器控制模型，运行效果良好(Rectifier control model of PSCAD, good results)

这是在MATLAB-2008a环境下编写的B样条曲面生成程序，可以通过调整节点矢量和控制顶点来调整曲面形状。(This is a MATLAB-2008a environment, prepared by B-spline surface generation program, you can adjust the knot vector and control points to adjust the surface shape.)

pscad高压直流输电背靠背工程CIGRE标准模型(pscad CIGRE HVDC back-engineering the Standard Model)

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)

说明：  函数绘图程序 VB 编写 可以绘制初高中 函数图像 支持颜色，精度修改 鼠标执针定位(VB function drawing program to prepare middle and high school mapping function can support color images, the accuracy of needle positioning modified mouse bailiff)
