Algorithm (Workflow)

This MATLAB function, named copyplot, is designed to copy the content of the current figure window into a new, randomly numbered figure window. It is part of the SolidGeometry library and was introduced in version 3.5. The function is useful for saving the content of figures that are about to be closed.

Input Parameters

The function copyplot does not take any input parameters. It operates on the current figure window, which is accessed using the gcf (get current figure) command.

Algorithm Steps

1. Retrieve the handle of the current figure using a = gcf;.
2. Capture the current figure's content as an image using I = getframe(gcf);. This stores the figure's content in the variable I, which contains the image data in I.cdata.
3. Create a new figure window with a random number as its identifier using figure(round(rand*10000));. The rand function generates a random number between 0 and 1, which is then multiplied by 10,000 and rounded to the nearest integer to create a unique figure number.
4. Display the captured image data in the new figure window using imshow(I.cdata);. The imshow function is used to display the image data stored in I.cdata.
5. Return focus to the original figure window using figure(a);. This ensures that the original figure remains the active window after the function executes.

Output

The function does not return any output variables. Instead, it creates a new figure window displaying the content of the original figure.

Use Case

The function is particularly useful when you want to preserve the content of a figure that is about to be closed, allowing you to continue working with the original figure while having a copy available for reference or further manipulation.
