Matlab如何在两条线之间填充颜色？ – MATLAB中文论坛

t = 0:0.1:10;

y = sin(t);

y2= 0.8*sin(t);

plot(t,y,t,y2,'r')

hold on

f=zeros(length(t),2);

i=1;

for t = 0:0.1:10;

f(i,1)=max([y(i),y2(i)]);

f(i,2)=min([y(i),y2(i)]);

i=i+1;

end

t = 0:0.1:10;

fy=cat(2,f(:,1)',flipdim(f(:,2),1)')';

fx=cat(2,t,flipdim(t',1)')';

fill(fx,fy,[0.2 0.5 0.9])
