Question

用matlab做当x和y的取值范围均为-2到2时．绘制出三维网线图

Answer 1

[X,Y]=meshgrid(0:1); X=[ nan X(1,:) nan nan X(:,1) X X(:,2) X(:,1) nan X(2,:) nan nan]; Y=[ nan Y(1,:) nan nan Y(:,1) Y Y(:,2) Y(:,1) nan Y(2,:) nan nan]; Z=ones(size(X)); Z(2:3,2:3)=0; mesh(X,Y,Z) axis equal axis off

Answer 2

有具体要求绘制的公式吗？举个例子，希望有所帮助。% By lyqmath
clc; clear all; close all;
[X, Y] = meshgrid(-2:0.1:2);
Z = peaks(X, Y);
mesh(X, Y, Z);
