find()

Core Math

find() is a MATLAB®-compatible core math function for indices of nonzero elements. optional second argument n limits the result count; optional third argument 'first' or 'last' picks which end to search from. Run it online in your browser with SimLab — free, no install, no license required.

Indices of nonzero elements. Optional second argument n limits the result count; optional third argument 'first' or 'last' picks which end to search from.

Syntax

find(x)
find(x, n)
find(x, n, 'first' | 'last')

Examples — run find() in your browser

find([0, 3, 0, 5, 0])
▶ Run
x = [5, 12, 8, 15, 3]; find(x > 10, 1, 'first')
▶ Run
x = [1, -2, 3, -4, -5, 6, -7]; find(x < 0, 3, 'last')
▶ Run

What does find() do?

Indices of nonzero elements. Optional second argument n limits the result count; optional third argument 'first' or 'last' picks which end to search from. It is a MATLAB®-compatible core math function available in SimLab with the same calling syntax as MATLAB® — typically: find(x).

Can I run find() in my browser?

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