matlab求教。z=[0:1:2],x=[0:0.5:3],在x《1时y=x+z；1<x《2，y=1+z：2<x《3，y=x+z-1.。求画出y的图形

Question

如题所述

Answer 1

clear all;

clc;

z=0:1:2;x=0:0.5:3;

[X,Z]=meshgrid(x,z);

[m,n]=size(X);

Y=zeros(m,n);

for i=1:m

    for j=1:n

        if X(i,j)<=1

            Y(i,j)=X(i,j)+Z(i,j);

        end

        if X(i,j)>1&&X(i,j)<=2

            Y(i,j)=1+Z(i,j);

        end

        if X(i,j)>2&&X(i,j)<=3

            Y(i,j)=X(i,j)+Z(i,j)-1;

        end

    end

end

surf(X,Z,Y);

结果：
