gradient()

Core Math

gradient() is a MATLAB®-compatible core math function for numerical gradient using central differences. interior points use central differences; edges use forward/backward differences. h is optional uniform spacing (default 1). Run it online in your browser with SimLab — free, no install, no license required.

Frequently Asked Questions about gradient()

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

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

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

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

What does gradient() do?

Numerical gradient using central differences. Interior points use central differences; edges use forward/backward differences. h is optional uniform spacing (default 1). It is a MATLAB®-compatible core math function available in SimLab with the same calling syntax as MATLAB® — typically: gradient(F).

Can I run gradient() in my browser?

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