matlab中怎样控制坐标轴范围
我的程序如下：
clear
w=10.^[-3:0.01:6];
R1=50;
R2=150;
Q=0.00001;
n=0.8;
r=50;
R0=150;
u=Q*w.^n*cos(pi*n/2);
v=Q*w.^n*sin(pi*n/2);
K=-R0*sqrt(2*w)/r; %K是一个矩阵
e=2.718281828;
a=0.5*sqrt(2)*r*(e.^(2*K).*sin(K)-1);
b=0.5*sqrt(2)*(2*e.^(2*K).*sin(K)-e.^(2*K)+1);
d=sqrt(w).*(e.^(2*K)+2*e.^(2*K).*cos(K)+1);
f=d*R1-a;
Z1=R1+[f.*(u.*f+b.*v+d)-b.*(v.*f-u.*b)]./[(u.*f+b.*v+d).^2+(v.*f-u.*b).^2];
Z2=-[b.*(u.*f+b.*v+d)+f.*(v.*f-u.*b)]./[(u.*f+b.*v+d).^2+(v.*f-u.*b).^2];
axis([0,400,0,150]);%控制坐标轴范围
plot(Z1,-Z2)
如果运行此程序的话,横坐标的范围是50-500,纵坐标范围是0-20.我想把横坐标变为0-400（每50为一个格）,纵坐标变为0-150（每50为一格）.
我用的是axis([0,400,0,150]) 但是貌似没用啊.
请问该怎样修改啊?

最后两行换一下顺序
即
plot(Z1,-Z2)
axis([0,400,0,150]);%控制坐标轴范围
把axis放在plot命令后面就可以了。
