Frequently Asked Questions about lsqnonneg()

Is the lsqnonneg() 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 lsqnonneg() and 510+ other MATLAB®-compatible function references at simulations4all.com/simlab.

Do I need to install MATLAB to use lsqnonneg()?

No. SimLab’s core parser, workspace state, and most functions run locally in your browser. The lsqnonneg() function requires no MATLAB® license or desktop software download.

What does lsqnonneg() do?

Solve the non-negative least-squares problem min ||C*x - d|| subject to x >= 0 using the Lawson-Hanson active-set algorithm. It is a MATLAB®-compatible optimization function available in SimLab with the same calling syntax as MATLAB® — typically: x = lsqnonneg(C, d).

Can I run lsqnonneg() in my browser?

Yes. Open SimLab at simulations4all.com/simlab, write or paste code that calls lsqnonneg(), and run it. This function’s calculation runs locally in the browser. SimLab session analytics, sharing, feedback, and eligible acceleration have separate network boundaries.
