Algorithm (Workflow)

This function, Videoquickcloseandopen, is part of the SG-Library and is used to manage video files created from figures. It is a simplified version of more complex video functions.

Input Parameters

• vw: This is the video writer object that is used to manage the video file.

Algorithm Steps

1. The function begins by calling drawnowvid, which likely updates the current figure or video frame.
2. The function retrieves the video writer object using getfuncparams with the first argument from varargin or the global Videoquick_vw.
3. If the video writer object vw is not empty, it constructs the full path of the video file by concatenating vw.Path, a file separator, and vw.Filename.
4. The video writer is then closed using the close function.
5. If the video writer object is empty, the function sets nn to an empty array.
6. If there are no output arguments (nargout==0), the function attempts to open the video file by calling openbydoubleclick with the constructed file path.

Global Variables

• Videoquick_vw: A global variable that may hold the default video writer object if not provided in the input arguments.

Assumptions

• The function assumes that drawnowvid and openbydoubleclick are defined elsewhere in the codebase.
• The function assumes that getfuncparams is a utility function to retrieve function parameters.
• The function assumes that the video writer object vw has properties Path and Filename.
