Frequently Asked Questions about residue()

Is the residue() function free to use in SimLab?

Yes. SimLab is 100% free — no signup, no license, and no usage limits. You can run residue() and 510+ other MATLAB®-compatible functions directly in your browser at simulations4all.com/simlab.

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

No. SimLab runs entirely in your web browser with zero installation. The residue() function works without any MATLAB® license or software download.

What does residue() do?

Partial fraction decomposition of transfer function b(s)/a(s). Returns residues r, poles p, and direct term k. It is a MATLAB®-compatible core math function available in SimLab with the same calling syntax as MATLAB® — typically: [r, p, k] = residue(b, a).

Can I run residue() in my browser?

Yes. Open SimLab at simulations4all.com/simlab, write or paste code that calls residue(), and run it. Execution happens locally in your browser — no data leaves your machine.
