matlab画三维图

mesh函数是用来画三维网格图的,但是要用meshgrid来产生格网矩阵!有时我们要在图上用标点来显示某些数值的重要性,就要用到mesh和plot3两个函数.>> [X,Y]=m

z=Fa.*cos(a)；x=(Fa.*sin(a)).*cos(b);y=(Fa.*sin(a)).*sin(b);%%错误代码中z,x,y的大小为1*100surf要z是方阵,不能是1列或者1行.

a=0:pi/50:2*pi;x=5*sin(a)+2*sin(5*a/3).*cos(a);y=5*cos(a)-2*sin(5*a/3).*sin(a);z=3-2*cos(5*a/3);plot

x=0:5;y=0:5;R=rand(6,6)z=R;[x,y]=meshgrid(x,y);mesh(x,y,z);这个已经在我电脑上试过了,可以的（7.0版的）

clearall;clc;x=-2:0.01:2;y=-2:0.01:2;z=0.5+(sin(x.^2+y.^2).^2-0.5)./(1.0+0.001*(x.^2+y.^2).^2);plot3

close all;clear all;clc;x = linspace(0,30,100); % 这里取了x上限30, 可根据需

帮你搜索到一个好的：function[data]=SquareDiamond(N,initvalue)%输入N为：方阵的维数2^N+1,在方阵的四个角的顶点上放置的初值,%这里定为四个初值一样%Exa

x=(1:100);y=(1:100);z=3*(1-x).^2.*exp(-(x.^2+(y+1).^2))-(0.2*x-x.^3-y.^5).*exp(-(x.^2-y.^2))-exp(-(x

clear,clc[x,y]=meshgrid(-1:0.05:1);z=sqrt(1-x.^2-y.^2);mesh(x,y,real(z));holdonmesh(x,y,-real(z));这样

gama=linspace(0,pi/2,10)theta=linspace(0,pi/2,10)r=1;[gg,tt]=meshgrid(gama,theta);%产生gama和theta的网格Kx

自己做的,不知可否.

clcclearp=[3.6,4.6,5.6,7.6,8.6];x=linspace(5,20,200);y=linspace(6.5,17.5,200);[xx,yy]=meshgrid(x,y);

a=0.4:0.05:1.0;b=0:0.05:1.0;[x,y]=meshgrid(a,b);z=259*(1.4+x+x.*y);mesh(x,y,z)

x=0:0.1:1;y=0:0.1:1;[x,y]=meshgrid(x,y);z=(60-100.*y+25.*x.^(1/2)).*(100.*y-55/2+15/2.*x)-120.*x./(1

[X,Y,Z]=meshgrid(...)surf(X,Y,Z).

看你那么有诚意去回答问题提高悬赏,我就帮你做吧,数据发到fjbylong@qq.com

画线用plot3();画面用surf();所以为plot3(A(:,1),A(:,2),A(:,3));或surf(A(:,1),A(:,2),A(:,3));

ezmesh('(y>=600)*2.37*10^8.*x.^0.8733.*exp(-0.0190*(y+273))+(y

x=0.1:0.001:1;y=1:.5:100;[X,Y]=meshgrid(x,y);Z=sqrt(0.5*(1+X))./(X.*Y);mesh(X,Y,Z);

%z的维数必须与xy形成网格的维数形同surf(x,y,z);mesh(x,y,z);
