parfor()

Programming

parfor() is a MATLAB®-compatible programming function for parallel-for loop keyword. simlab accepts parfor for matlab source compatibility and desugars it to an ordinary for loop at parse time, so the body runs serially in iteration order. use it when porting code that contains parfor; results match the equivalent for loop. Run it online in your browser with SimLab — free, no install, no license required.

Syntax

parfor i = range
  ...
end

Examples — run parfor() in your browser

s = 0;
parfor i = 1:5
  s = s + i;
end
s

▶ Run

Limitations

Runs serially (desugared to for); no real multi-worker parallelism.

Frequently Asked Questions about parfor()

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

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

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

What does parfor() do?

Parallel-for loop keyword. SimLab accepts parfor for MATLAB source compatibility and desugars it to an ordinary for loop at parse time, so the body runs serially in iteration order. Use it when porting code that contains parfor; results match the equivalent for loop. It is a MATLAB®-compatible programming function available in SimLab with the same calling syntax as MATLAB® — typically: parfor i = range ... end.

Can I run parfor() in my browser?

Yes. Open SimLab at simulations4all.com/simlab, write or paste code that calls parfor(), and run it. This function’s calculation runs locally in the browser. SimLab session analytics, sharing, feedback, and eligible acceleration have separate network boundaries.
