matlab做出曲面x^2 y^2=2z 的图形.

clear>>symsxy>>z=x.*y;>>ezsurf(x,y,z)我就已经实现好了你也试试吧

[X,Y]=meshgrid(linspace(-10,10),linspace(-10,10));Z=(X.^2)/(4^2)-(Y.^2)/(5^2);mesh(X,Y,Z)

x=0:.1:2*pi;y=exp(-0.2*x).*sin(0.5*x);[zz,yy,xx]=cylinder(y);xx=xx*2*pi;surf(xx,yy,zz)再问：[zz,yy,xx]=

代码如下：xx=-1:0.1:1;[xy]=meshgrid(xx);z=2-x.^2-y.^2;surf(x,y,z)

x=-1:.1:1;y=x;[X,Y]=meshgrid(x,y);z=6-X.^2-Y.^2;mesh(X,Y,z)z1=X.^2+Y.^2;mesh(X,Y,z1)你试试能不能用!

三维曲线绘图t=(0:0.02:2)*pi;x=sin(t);y=cos(t);z=cos(2*t);plot3(x,y,z,'b-',x,y,z,'bd'),view([-82,58]),boxon

你看看这个就知道了：http://zhidao.baidu.com/question/175906491.html?si=9

clfx=-4:4;y=x;\x09\x09\x09\x09[X,Y]=meshgrid(x,y);\x09Z=sqrt(X.^2+Y.^2);\x09\x09\x09\x09)surf(X,Y,Z)

采用插值法知道了一些点(x,y,z)坐标,怎样用MATLAB绘制出三维曲面?至于做出拟合函数z=f（x,y）可以输入sftool启动曲面拟合工具箱,输入xyz数据选用合适的函数拟合

应该先绘制曲面z=xy.matlab程序如下：x=-30:1:30;y=-30:1:30;n=length(x);[xb,yb]=meshgrid(x,y);zb=xb.*yb;%要用xb,yb而不是

A=[1.486,3.059,0.1;2.121,4.041,0.1;2.570,3.959,0.1;3.439,4.396,0.1;4.505,3.012,0.1;3.402,1.604,0.1;2

x=-1:.1:1;%x的取值y=-1:.1:1;%y的取值[x,y]=meshgrid(x,y);z=x.*y;surf(x,y,z);

x=[1;2;3;4;5;6],y=[1;2;3;4;5;6],z=[5;8;4;9;6;1],scatter(x,y,5,z)%散点图figure[X,Y,Z]=griddata(x,y,z,lin

ezmesh('sqrt(4-x^2-y^2)')

请问你这是球坐标还是直角坐标?clcclear[x,y]=meshgrid(0:0.01*pi:2*pi);z=sin(x).*cos(y);surf(x,y,z);[T,P,R]=cart2sph(

画曲面---把曲面方程参数化a1=linspace(0,2*pi,30);b1=linspace(0,pi,30);[a,b]=meshgrid(a1,b1);x=6*cos(a).*sin(b);y

很怪异的函数：clearall;clc;z=@(x,y)((x-22).^2+(y-22).^2).^(-20);ezsurf(z,[21.6,22.4],[21.6,22.4]);

[x,y]=meshgrid(0:0.01:2);z=1000.*[log(x)./log(y)];mesh(x,y,z)

ezmesh('0.2*x/sqrt(x+x*(x-1)*y)',[0 20 0 1])

functionz=poll_example(x,y)z=(100+0.1*x.^0.5+10.9*y.^0.5).*(25
