How does one typically implement a "Library"?

I have several MATLAB projects that I reuse frequently. Often I want to take functions or classes from multiple projects and use them in a new one—essentially creating a shared "library" of code.

What’s the best practice for organizing and reusing code across projects?

These are the approaches I’ve considered, and their issues:

• Copying code into the new project – easy at first, but hard to maintain when the original code changes.
• Adding project folders to the MATLAB path – works, but can lead to name conflicts if different projects contain files/functions with the same name.
• Namespace (+folder) packages – solves name conflicts and keeps things organized, but scripts inside a namespace can't automatically see other scripts in the same folder unless you prefix everything with the package name (e.g., package.func). This isn’t practical when dealing with large or third-party codebases.

Ideally, I want MATLAB to:

• Let scripts call other scripts/functions located in the same folder without changing the current working directory, and
• Avoid name conflicts across projects,
• Without needing to rewrite existing code to add namespace prefixes everywhere.

This seems to be what toolboxes do.

How do people typically manage this in MATLAB? Is there a clean way to build a reusable code library from multiple projects without duplicating code or modifying everything to use package prefixes?

I think this is what you're getting at

No not really. Using "projects" is a way of build projects using external code but it's two fold. I some matlab projects to be easily accessible without having to worry about name conflicts and I'd like to be able to build projects using other projects without needing to modify their source. Something like a mix of namespace folders and addpath where I can access projects without adding to path, keeping the execution scoped interally to the component namespace folder strucuture.
