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:)

MATLAB三次样条插值法 求信号的包络线 源代码(MATLAB cubic spline interpolation method for the signal envelope source code)

说明：  绘制磁滞回线，模拟磁滞回线产生的过程，便于理论分析建模(Drawing hysteresis loops to simulate the process of hysteresis loops is convenient for theoretical analysis and modeling.)

选择画图区的点从而绘制B样条曲线，是计算机图形学中一个重要的实例。使用MFC做的。(select some points in the painting area to paint B-Spline curves)

CAD批量打印源码程序，例程结合易语言应用接口支持库、拖放支持库、扩展功能支持库，创建Autocad.Application对象，实现CAD对象的属性、方法，可以批量打印。(CAD batch printing source programs, routines combined with easy language support library application interface , drag and drop support libraries , extensions support library , create Autocad.Application object implementing the CAD object s properties , methods, you can batch print .)

说明：  scatterbar就是画出三维散点柱状图，并且可以调整柱子的大小和颜色渐变，比原函数bar3更方便，更好用。(scatterbar is to draw three-dimensional scatter histogram, and can adjust the size and color gradients pillars, and more convenient than the original function bar3, easier to use)

MATLAB下绘制三维极坐标图，输入极径和角度范围，还可以选择画图的种类，也可以画等高线图(Draw three-dimensional polar plot using MATLAB.)

用VC做的一个水泵的图..图中圆形水泵有渐变效果!(Using VC do a water pump picture... Figure in a circular water pump gradual change effect!)
