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.
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.
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.

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. Execution happens locally in your browser — no data leaves your machine.
