用四阶龙格-库塔法求系统在U单位阶跃输入下该系统的响应曲线(Using the four order Runge Kutta method to find the response 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:)

软件可以实现对时域范围内的摩擦力的数据处理，同时可以对显示二维的摩擦力随时间变化规律及三维角度的摩擦力-位移-时间三变量的变化规律，最后可以将所绘制的图像进行导出。(The software can realize the data processing of the friction in the time domain, and can change the friction law of the two-dimensional friction and the three-dimensional friction-displacement-time three variables. Finally, Image is exported.)
