Do I need to install MATLAB to use chi2inv()?
No. SimLab’s core parser, workspace state, and most functions run locally in your browser. The chi2inv() function requires no MATLAB® license or desktop software download.
What does chi2inv() do?
Inverse chi-squared CDF (quantile function). Returns x such that chi2cdf(x, df) = p. Uses Newton iteration with Wilson-Hilferty initial guess. It is a MATLAB®-compatible statistics function available in SimLab with the same calling syntax as MATLAB® — typically: chi2inv(p, df).
Can I run chi2inv() in my browser?
Yes. Open SimLab at simulations4all.com/simlab, write or paste code that calls chi2inv(), and run it. This function’s calculation runs locally in the browser. SimLab session analytics, sharing, feedback, and eligible acceleration have separate network boundaries.
