在 MATLAB Online 中打开

Im getting a strange error from the following:

 vv = VideoWriter('animated.avi', 'Uncompressed AVI');
    vv.FrameRate = 30;
    vv.Quality = 75;
    open(vv)
    writeVideo(vv,frame1)
    close(vv)
    

The error is the same as the title: 'Unable to use a value of type 'VideoWriter' as an index'

You have an existing variable named open or writeVideo or close so MATLAB thinks you are trying to index that variable.
