This MATLAB function plots the parametric curve xt = x(t), yt = y(t), and zt = z(t) over the default interval –5 < t < 5.
用fplot 函数。例子来自官方文档。% Plot the parametric curve x = cos(3*t) and y = sin(2*t). syms t x = cos(3*t); y = sin(2*t); fplot(x,y)若参数方程中有 分段函数,则使用 piecewise 函数。用法参考文章…

The fplot3 function is used to draw three-dimensional parametric curves. It accepts three function handles as input parameters: funx, funy, and funz. These handles define the coordinate positions of points on the curve in the three dimensions of x, y, and z. In order to construct this cu...
