- 粗糙图
原始图像
clear all;
x=-2*pi:0.01:2*pi;
y1=sin(x);
y2=cos(x);
plot(x,y1)
hold on
plot(x,y2)
以上代码就是上面粗糙图代码，图像实在是难看啊！！！下面看看怎么优化吧。
优化后图像
clear all;
x=-2*pi:0.01:2*pi;
y1=sin(x);
y2=cos(x);
plot(x,y1,'r-','linewidth',2)
hold on
plot(x,y2,'b-','linewidth',2)
xlim([-6.3 6.3])
legend('y_1=sin(x)','y_2=cos(x)')
xlabel x
ylabel y
set(gca,'linewidth',1,'fontsize',16)
set(gca,'xtick',-2*pi:pi:pi*2,'xticklabel',...
{'-2pi','-pi','0','pi','2pi'})
