Containers
keys() is a MATLAB®-compatible containers function for return all keys of a containers.map as a cell array, in insertion order. (for a math.js object, falls through to the math.js builtin.). Run it online in your browser with SimLab — free, no install, no license required.

Frequently Asked Questions about keys()
Is the keys() function free to use in SimLab?
The browser workspace requires no MATLAB® license or installation. Connected features require network access and may have account, tier, availability, or usage limits. You can open keys() and 510+ other MATLAB®-compatible function references at simulations4all.com/simlab.
Do I need to install MATLAB to use keys()?
No. SimLab’s core parser, workspace state, and most functions run locally in your browser. The keys() function requires no MATLAB® license or desktop software download.
What does keys() do?
Return all keys of a containers.Map as a cell array, in insertion order. (For a math.js object, falls through to the math.js builtin.). It is a MATLAB®-compatible containers function available in SimLab with the same calling syntax as MATLAB® — typically: m.keys().
Can I run keys() in my browser?
Yes. Open SimLab at simulations4all.com/simlab, write or paste code that calls keys(), and run it. This function’s calculation runs locally in the browser. SimLab session analytics, sharing, feedback, and eligible acceleration have separate network boundaries.
