matlab legend标注问题
%图形输出
clear all;
[x,y]=meshgrid(0:0.01:1);
%生成以0.01为间距的网络格点
a=0:.001:1;
b=sqrt(1-a.^2);
figure(2);
plot(x,y,'.b',a,b,'r','linewidth',5);
legend('网格点','单位圆圆弧');
xlabel('x');
ylabel('y');

为什么标注出来的单位圆圆弧前面的符号也是点
matlab legend标注问题%图形输出clear all;[x,y]=meshgrid(0:0.01:1);%生成以0.01为间距的网络格点a=0:.001:1;b=sqrt(1-a.^2);figure(2);plot(x,y,'.b',a,b,'r','linewidth',5);legend('网格点','单位圆圆弧');xlabel('x');ylabel('y');titl
就因为你的x和y是101*101的矩阵,不是向量,所以画出来的结果就是这样的了
用这个程序就能够解决问题了
[x,y]=meshgrid(0:0.01:1);
%生成以0.01为间距的网络格点
a=0:.001:1;
b=sqrt(1-a.^2);
figure(2);
plot(a,b,'r',x,y,'.b',a,b,'r','linewidth',5);
legend('单位圆圆弧','网格点');
xlabel('x');
ylabel('y');
