Please do tell me whether this possible- or suggest the closest solution.

Hello. You can save an animated figure using VideoWriter() function. For example ,

 writerObj = VideoWriter('example.avi');
 writerObj.FrameRate = 60;
 open(writerObj);

 Z = peaks; surf(Z); 
 axis tight
 set(gca,'nextplot','replacechildren');
 set(gcf,'Renderer','zbuffer');

 for k = 1:20 
   surf(sin(2*pi*k/20)*Z,Z)
   frame = getframe;
   writeVideo(writerObj,frame);
 end

 close(writerObj);

The animated plot is saved as an .avi file.

Thanks. I manage to adapt it to my code. I get this error

Error using VideoWriter/writeVideo (line 383)
Frame must be 436 by 344

    Error in videoooo (line 125)
    writeVideo(writerObj,frame);

I can't really be much help unless I see your code. However, these links ( 1 and 2 ) might be useful for fixing your error.

When you use VideoWriter, every frame must be exactly the same size.

I am capturing the frames during plotting. In fact, I am having lots of for loop which are generating plots. Can I force the frames to be the same size for all the plots?
