Matlab：使用avifile，addframe，getframe;生成的avi被扭曲

aviobj = avifile( \'weights.avi\' );
for jj = 1:whatever
  % do some training
  imagesc( ... ); % where \'...\' is stuff to reshape the weight matrix
  aviobj = addframe( aviobj, getframe );
end;
aviobj = close( aviobj );
implay( \'weights.avi\' );

aviobj = avifile( \'weights.avi\' );
fig = figure;
for jj = 1:whatever
  % do some training

  axis off;
  aviobj = addframe( aviobj, getframe( fig ) );
end;
aviobj = close( aviobj );
implay( \'weights.avi\' );
