I use MATLAB2012a, you can try if this function works for you. The input arguments are: the path to the images (vide_dir), extention of the images (extension), path and name of the video with extension (aviname), and the frame rate (fps)
For example: make_video('/home/user/myImages/','jpg','myvideo.avi',5)
function make_video(video_dirs,extension,aviname,fps)
      resnames=dir(fullfile(video_dirs,['*.' extension]));
      aviobj=VideoWriter(aviname);
      aviobj.FrameRate=fps;
      open(aviobj);
      for i=1:length(resnames)
          img=imread(fullfile(video_dirs,resnames(i).name));
          F=im2frame(img);
          if sum(F.cdata(:))==0
              error('black');
          end
          writeVideo(aviobj,F);
      end
      close(aviobj);
end
