Frequently Asked Questions about fitcknn()
Is the fitcknn() 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 fitcknn() and 510+ other MATLAB®-compatible function references at simulations4all.com/simlab.
Do I need to install MATLAB to use fitcknn()?
No. SimLab’s core parser, workspace state, and most functions run locally in your browser. The fitcknn() function requires no MATLAB® license or desktop software download.
What does fitcknn() do?
Fit a k-nearest-neighbor classifier with k neighbors, backed by ml.js. It is a MATLAB®-compatible machine learning function available in SimLab with the same calling syntax as MATLAB® — typically: mdl = fitcknn(X, y).
Can I run fitcknn() in my browser?
Yes. Open SimLab at simulations4all.com/simlab, write or paste code that calls fitcknn(), and run it. This function’s calculation runs locally in the browser. SimLab session analytics, sharing, feedback, and eligible acceleration have separate network boundaries.
