yy-sin.m

这是matlab编程的一个例子

x=0:0.0645:0.4515;
y=8*sin(13.96*x);
plot(x,y,'b*-')
theAxes=axis;
fmat=moviein(30);
for j=1:30
    y=8*sin(13.96*x-j*2*pi/30);
    z=0;
    plot(x,y,'b*-',x,z,'r*-',(x+0.0215),z,'r--',(x+0.043),z,'r--')
    axis([0 0.5 -10 10])
    fmat(:,j)=getframe;
end
movie(fmat,30);
