Frequently Asked Questions about cwt()

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

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

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

What does cwt() do?

Continuous wavelet transform. Decomposes a signal into time-scale (time-frequency) components using wavelets. Default wavelet is Morlet. It is a MATLAB®-compatible signal processing function available in SimLab with the same calling syntax as MATLAB® — typically: cwt(x).

Can I run cwt() in my browser?

Yes. Open SimLab at simulations4all.com/simlab, write or paste code that calls cwt(), and run it. This function is marked server-only. It is not a local-only calculation, and the call fails closed when its server implementation is unavailable.
