Algorithm (Workflow)

This algorithm is designed to restore the parameters of a current figure/view in MATLAB. It relies on a global variable sview_V that stores the view parameters set by a previous function call, presumably sview.

Input Parameters

• varargout: This is a variable-length output argument list, allowing the function to return multiple outputs if needed. However, in this function, it is not utilized.

Global Variable

• sview_V: A global structure that holds the view parameters such as azimuth, elevation, position, camera view angle, camera target, and camera position.

Algorithm Steps

1. Check if sview_V is not empty. This indicates that the view parameters have been previously set using sview.
2. If sview_V is not empty:
   • Use the view function to set the azimuth and elevation of the current axes to sview_V.a and sview_V.e, respectively.
   • Set the position of the current figure using set(gcf, 'Position', sview_V.get.Position).
   • Set the camera view angle, target, and position of the current axes using set(gca, ...) with the respective fields from sview_V.
   • Call VLFLshow, which is likely a custom function to update the view or enable interactive rotation (as suggested by the commented rotate3d).
3. If sview_V is empty:
   • Check if there are any input arguments (nargin > 0). If there are, the function does nothing further.
   • If there are no input arguments, display a warning message indicating that the view has not been defined by sview yet.

The function is part of a visualization library and is used to restore a previously saved view configuration for MATLAB figures.
