MATLAB动图的问题

Question

以下是一个输出动图的程序：figure;frames_images = cell(1, (41-1)/5 + 1);for i=1:5:41 pcolor(xmesh/20,ymesh/20,vor_phase_ave(:,:,i)*20/42); shading interp; axis equal tight; axis([0 5 -3 3]); hold on; fill([0,0.5,0.5,0],[-3,-3,-0.5,-0.5],'w') fill([0,0.5,0.5,0],[-0.5,-0.5,0.5,0.5],'k');hold on; fill([0,0.5,0.5,0],[0.5,0.5,3,3],'w'); set(gca,'FontName','Times New Roman','FontSize',12); text(-1,0,'\ity/\itD ','FontSize', 14, 'FontName', 'times new roman'); text(2.5,-3.4,'\itx/\itD ','FontSize', 14, 'FontName', 'times new roman'); set(gca,'LineWidth',1.5); colormap jet; caxis([-10 10]); drawnow; frames_images{(i-1)/5 + 1} = frame2im(getframe(gcf)); waitforbuttonpress; endfilename = 'vordongtu2.gif';for idx = 1:length(frames_images) [A, map] = rgb2ind(frames_images{idx}, 256); if idx == 1 imwrite(A, map, filename, 'gif', 'LoopCount', Inf, 'DelayTime', 1); else imwrite(A, map, filename, 'gif', 'WriteMode', 'append', 'DelayTime', 1); end end
现在我想要每一个动图上都有一个标题，标题的程序为 text(2,3.5,'{\it\Phi} = (i-1)*0.05\pi ','FontSize', 14, 'FontName', 'times new roman'); end目的是为了标题也能随动图的变化而变化，而且后面的图的数字要覆盖前面的数字，最后不能堆在一起，应该如何在原程序中添加，麻烦直接在原程序中添加。

以下是修改后的程序： figure; frames_images = cell(1, (41-1)/5 + 1); for i=1:5:41

pcolor(xmesh/20,ymesh/20,vor_phase_ave(:,:,i)*20/42);
shading interp;
axis equal tight;
axis([0 5 -3 3]);
hold on;
fill([0,0.5,0.5,0],[-3,-3,-0.5,-0.5],'w')
fill([0,0.5,0.5,0],[-0.5,-0.5,0.5,0.5],'k');
hold on;
fill([0,0.5,0.5,0],[0.5,0.5,3,3],'w');
set(gca,'FontName','Times New Roman','FontSize',12);
text(-1,0,'{\ity}/{\itD}','FontSize', 14, 'FontName', 'times new roman');
text(2.5,-3.4,'{\itx}/{\itD}','FontSize', 14, 'FontName', 'times new roman');
set(gca,'LineWidth',1.5);
colormap jet;
caxis([-10 10]);

% Add title
title_str = sprintf('{\\it\\Phi} = %.2f\\pi', (i-1)*0.05);
text(2,3.5,title_str,'FontSize',14,'FontName','times new roman');

drawnow;
frames_images{(i-1)/5 + 1} = frame2im(getframe(gcf));
waitforbuttonpress;

end filename = 'vordongtu2.gif'; for idx = 1:length(frames_images) [A, map] = rgb2ind(frames_images{idx}, 256); if idx == 1 imwrite(A, map, filename, 'gif', 'LoopCount', Inf, 'DelayTime', 1); else imwrite(A, map, filename, 'gif', 'WriteMode', 'append', 'DelayTime', 1); end end 在每个循环中添加了一个修改后的代码，用于添加标题： % Add title title_str = sprintf('{\it\Phi} = %.2f\pi', (i-1)*0.05); text(2,3.5,title_str,'FontSize',14,'FontName','times new roman'); 这个代码会在每一帧的上方添加一个标题，标题的内容为"Φ=xxπ"，其中xx为当前的循环变量i减一乘以0.05。使用sprintf函数将字符串格式化后传给text函数，即可完成标题的添加。 另外，为了保证后面的数字能覆盖前面的数字，title函数的默认行为是在当前图的上方添加标题，而不是在每张图像的位置添加标题。因此我们使用text函数来添加标题，并在每张图像的上方设置一段空白区域，使得后面的标题能够将前面的标题覆盖。
