decimate()
Signal Processing
decimate() is a MATLAB®-compatible signal processing function for downsample signal by integer factor r. Run it online in your browser with SimLab — free, no install, no license required.
Downsample signal by integer factor r.
Syntax
decimate(x, r)
Examples — run decimate() in your browser
decimate([1, 2, 3, 4, 5, 6, 7, 8, 9, 10], 2)▶ Run
Limitations
Uses block averaging instead of MATLAB anti-aliasing Chebyshev filter. May introduce aliasing artifacts.

Frequently Asked Questions about decimate()
Is the decimate() 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 decimate() and 510+ other MATLAB®-compatible function references at simulations4all.com/simlab.
Do I need to install MATLAB to use decimate()?
No. SimLab’s core parser, workspace state, and most functions run locally in your browser. The decimate() function requires no MATLAB® license or desktop software download.
What does decimate() do?
Downsample signal by integer factor r. It is a MATLAB®-compatible signal processing function available in SimLab with the same calling syntax as MATLAB® — typically: decimate(x, r).
Can I run decimate() in my browser?
Yes. Open SimLab at simulations4all.com/simlab, write or paste code that calls decimate(), and run it. This function’s calculation runs locally in the browser. SimLab session analytics, sharing, feedback, and eligible acceleration have separate network boundaries.
