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
mesh(X,Y,z);
x=linspace(0,135,136);
y=[1463.1 1450.7 1391.6 1346 1243.8 1131.4 1030.1 925.47 825.45 749.11 673.8 624.92 579.37 544.9 516.15 494.1 477.52 463.43 451.71 441.51 434.96 428.27 424.46 420.52 419.57 417.39 415.12 413.6 412.24 410.6 410.32 408.96 408.34 406.43 403.34 401.32 399.89 395.76 394.58 392.32 390.04 388.16 385.06 384.21 383.54 382.39 380.55 381.21 381.58 380.53 379.2 379.24 377.92 377.17 377.49 377.35 377.78&nbs
