哪位能用MATLAB演示曲线 y=e的-x/3次方绕 x轴旋转产生旋转曲面的过程

matlab将一条曲线的绕x轴旋转几何体图画出来

这是绘制旋转曲面网格图的程序,该程序可以绘制任意曲线沿任意旋转轴生成的旋转曲面。

把该文件保存到你的工作目录中即可。

用法说明:

rotsurf(curve,alpha,dirct,orgin)

curve=[x,y,z]为母线,其中x,y,z为列向量,分别代表母线的三维坐标

向量alpha为旋转的弧度,默认为0:pi/36:2*pi,采样点的范围和密度都可以手动控制

direct和origin分别代表旋转轴的方向和该旋转轴上的任意一点的坐标,这两个参数合起来确定了一条直线,即旋转轴,其中:

direct表示旋转轴的方向,有两种表示法[theta,phi]或[x0,y0,z0],其中:

theta代表沿xoy平面从x轴正方向逆时针旋转的弧度,phi代表从xoy平面向z轴正方向旋转的弧度

[x0,y0,z0]代表方向向量

direct默认为[0 0 1],即z轴方向

origin=[xo,yo,zo]为该旋转轴上的任意一点坐标,默认为[0 0 0]即原点

h=rotsurf(...)

绘制曲面的同时返回该曲面的句柄h


例:绘制母线为x=0,y^2+z^2=1,旋转轴为x=1,z=-y-2的圆环

t=linspace(-pi,pi,37);
y=sin(t);z=cos(t);x=y-y;
rotsurf([x'y'z'],[],[0-11],[1-20])
xlabel('x');ylabel('y');zlabel('z');axisequal



用matlab怎么绘制一条曲线绕纵轴旋转生成的曲面?

x=linspace(0,135,136);

y=[1463.11450.71391.613461243.81131.41030.1925.47825.45749.11673.8624.92579.37544.9516.15494.1477.52463.43451.71441.51434.96428.27424.46420.52419.57417.39415.12413.6412.24410.6410.32408.96408.34406.43403.34401.32399.89395.76394.58392.32390.04388.16385.06384.21383.54382.39380.55381.21381.58380.53379.2379.24377.92377.17377.49377.35377.78377.78378.16378.3378.17381.65381.52383.12385.37300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300300];

如何用matlab编写程序实现曲面的旋转

引入角度alpha和半径R,假设曲线z = f(R)是绕z轴旋转: clc,clear alpha=0:pi/50:2*pi; %角度[0,2*pi] R=0:0.1:10; %半径 x = R.*cos(alpha); y = R.*sin(alpha); [X,Y] = meshgrid(x,y); z = f(sqrt(X.^2+Y.^2)); %z = f(R),R^2 = x^2 + y^2 me.
