Matlab绘制动态图的两种方式（参考） MATLAB

第一种方式

close all; clear all; clc; clf; xlabel('X轴'); ylabel('Y轴'); box on; axis([-2,2,-2,2]); axis equal; pause(1); h=line(NaN,NaN,'marker','o','linesty','-','erasemode','none'); t=6*pi*(0:0.02:1); for n=1:length(t) set(h,'xdata',2*cos(t(1:n)),'ydata',sin(t(1:n))); pause(0.05); frame=getframe(gcf); imind=frame2im(frame); [imind,cm] = rgb2ind(imind,256); if n==1 imwrite(imind,cm,'test.gif','gif', 'Loopcount',inf,'DelayTime',1e-4); else imwrite(imind,cm,'test.gif','gif','WriteMode','append','DelayTime',1e-4); end end
