Algorithm (Workflow)

This algorithm is a MATLAB function named togglefig that toggles the position of the current figure window between a default position and its original position. It is part of the SolidGeometry library and was introduced in version 4.3.

Input Parameters

The function does not take any input parameters. It operates on the current figure window obtained using gcf (get current figure).

Persistent Variable

The function uses a persistent variable fpos to store the original position of the figure window. This variable retains its value between function calls.

Algorithm Steps

1. Retrieve the screen size using get(get(gcf,'Parent'),'ScreenSize') and store it in ss.
2. Define a default figure size fs as [560 420].
3. Calculate the default position defpos for the figure window using the screen size and default figure size. The default position is set to the top-left corner of the screen with a margin of 100 units from the top.
4. Get the current position of the figure window using get(gcf,'Position') and store it in actpos.
5. If fpos is empty, initialize it with defpos.
6. Check if the current position actpos is not equal to the default position defpos:
• If true, set the figure position to defpos and update fpos with actpos.
• If false, set the figure position to fpos.
7. Use shg to bring the figure window to the front.

Example Usage

The function can be used as follows:

SGfigure; 
set(gcf,'Position',[100 200 300 400]);
togglefig; 
pause(1); 
togglefig; 
pause(1); 
togglefig;

This example creates a figure, sets its position, and then toggles its position twice with a pause of 1 second between each toggle.
