matlab三维图中如何画y=1 2x 12-搜答案-大师作文网

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

用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

[x,y,z]=griddata(X,Y,Z,linspace(min(X),max(X))',linspace(min(Y),max(Y)),'v4');surf(x,y,z)或者mesh(x,y,

clc;clear;a=0:pi/100:pi;b=0:pi/100:pi;c=0:pi/50:2*pi;x=(sin(a)+sin(a+b)).*cos(c);y=sin(a)+cos(b);z=c

clf;shg,x=3*pi*(-1:0.05:1);y=x;[X,Y]=meshgrid(x,y);Z=X.*Y;h=surf(X,Y,Z);colormap(jet);axisoffn=12;mm

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

x=1:1:3;y=0.1:0.1:2;[x,y]=meshgrid([x,y]);z=x.^2./y;plot3(x,y,z);gridon

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

plot3(X1,Y1,Z1);例如plot3(sin(t),cos(t),t) 再问：使用plot3（）指令时，为什么出现errorusing*的程序错误？x=138*cos（t）再问：x

[x,y]=meshgrid(-1:0.01:1);z=x.^2+y.^2;surfl(x,y,z)

matlab 画三维图

自己做的,不知可否.

x=15:5:65;y=20:10:100;R=rand(9,11);mesh(x,y,R)

x=-1:0.05:1;y=-1:0.05:1;[x,y]=meshgrid(x,y);z=sqrt(1+x.*x-y.*y);z(y

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)

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

要进行插值,x不能有重复的数,必须x与y一一对应,形成数据对

=log10([0.0001 0.001 0.01 0.1 1]);[x y]=meshgrid(r);z=[0.3899 0.3829&n

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);
