Frequently Asked Questions about projinv()
Is the projinv() function free to use in SimLab?
Yes. SimLab is 100% free — no signup, no license, and no usage limits. You can run projinv() and 510+ other MATLAB®-compatible functions directly in your browser at simulations4all.com/simlab.
Do I need to install MATLAB to use projinv()?
No. SimLab runs entirely in your web browser with zero installation. The projinv() function works without any MATLAB® license or software download.
What does projinv() do?
Inverse map projection (proj4-backed): convert projected (x, y) back to geographic (lat, lon). It is a MATLAB®-compatible mapping function available in SimLab with the same calling syntax as MATLAB® — typically: [lat, lon] = projinv(proj, x, y).
Can I run projinv() in my browser?
Yes. Open SimLab at simulations4all.com/simlab, write or paste code that calls projinv(), and run it. Execution happens locally in your browser — no data leaves your machine.
