fit()
Curve Fitting
fit() is a MATLAB®-compatible curve fitting function for fit a model to data. fittype is a fittype object or a library name such as 'poly2', 'exp1', 'gauss1', 'fourier1', 'power1'. returns a fit object you can evaluate with fnval/feval and optional goodness-of-fit stats. Run it online in your browser with SimLab — free, no install, no license required.

Frequently Asked Questions about fit()
Is the fit() 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 fit() and 510+ other MATLAB®-compatible function references at simulations4all.com/simlab.
Do I need to install MATLAB to use fit()?
No. SimLab’s core parser, workspace state, and most functions run locally in your browser. The fit() function requires no MATLAB® license or desktop software download.
What does fit() do?
Fit a model to data. fitType is a fittype object or a library name such as 'poly2', 'exp1', 'gauss1', 'fourier1', 'power1'. Returns a fit object you can evaluate with fnval/feval and optional goodness-of-fit stats. It is a MATLAB®-compatible curve fitting function available in SimLab with the same calling syntax as MATLAB® — typically: cfit = fit(x, y, fitType).
Can I run fit() in my browser?
Yes. Open SimLab at simulations4all.com/simlab, write or paste code that calls fit(), and run it. This function’s calculation runs locally in the browser. SimLab session analytics, sharing, feedback, and eligible acceleration have separate network boundaries.
