matlab 三維畫圖總結

1.畫函數的三維圖，如：Z(X,Y)=2*X.*exp(-X.^2-Y.^2)+1;

close all;
[X,Y]=meshgrid(-2:0.5:2,-2:0.5:2);%生成坐标軸
Z=2*X.*exp(-X.^2-Y.^2)+1;%Z是X,Y的函數

num=0;
num=num+1;
subplot(2,3,num);
plot3(X,Y,Z);
axis([-3 3 -3 3 0 2]);%限定顯示的範圍
xlabel('x軸');%x軸坐标
ylabel('y軸');%y軸坐标
zlabel('z軸');%z軸坐标
title('http://blog.csdn.net/nuptboyzhb/   figure(1)');%标題
