Algorithm (Workflow)

The function closeall is a simple auxiliary procedure designed to close all open figures and files in a MATLAB environment. It is part of the SolidGeometry library and was introduced in version 1.0. The function is particularly useful in experiments where script characters are used, as it ensures that all graphical windows and file handles are closed, preventing any potential conflicts or resource leaks.

Input Parameters

The closeall function does not take any input parameters. It operates globally on the MATLAB environment to close all open figures and files.

Functionality

The function consists of a single line of code:

close all;

This command is a built-in MATLAB function that closes all open figure windows. It is equivalent to executing close('all'), which explicitly specifies that all figures should be closed.

Use Case

The closeall function is typically used in scripts and functions where it is necessary to ensure that no residual figures or file handles remain open from previous operations. This is particularly important in iterative processes or when running multiple scripts sequentially, as open figures can consume system resources and lead to unexpected behavior.

Conclusion

The closeall function is a straightforward utility that enhances the robustness of MATLAB scripts by ensuring a clean slate in terms of open figures and files. Its simplicity and effectiveness make it a valuable tool in the SolidGeometry library.
