Frequently Asked Questions about kalman()

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

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

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

What does kalman() do?

Steady-state Kalman filter gain, computed via LQR duality. Qn is process noise covariance, Rn is measurement noise covariance. It is a MATLAB®-compatible control systems function available in SimLab with the same calling syntax as MATLAB® — typically: [Kf, P, e] = kalman(A, C, Qn, Rn).

Can I run kalman() in my browser?

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