varargin()
Programming
varargin() is a MATLAB®-compatible programming function for special parameter name that collects all extra positional arguments into a cell array. index with `varargin{i}` and use `length(varargin)` for the count. Run it online in your browser with SimLab — free, no install, no license required.
Special parameter name that collects all extra positional arguments into a cell array. Index with `varargin{i}` and use `length(varargin)` for the count.
Syntax
function out = myfn(varargin)
function out = myfn(a, b, varargin)
Examples — run varargin() in your browser
function s = sumall(varargin)
s = 0;
for i = 1:length(varargin)
s = s + varargin{i};

Frequently Asked Questions about varargin()
Is the varargin() function free to use in SimLab?
The browser workspace requires no MATLAB® license or installation. Connected features require network access and may have account, tier, availability, or usage limits. You can open varargin() and 510+ other MATLAB®-compatible function references at simulations4all.com/simlab.
Do I need to install MATLAB to use varargin()?
No. SimLab’s core parser, workspace state, and most functions run locally in your browser. The varargin() function requires no MATLAB® license or desktop software download.
What does varargin() do?
Special parameter name that collects all extra positional arguments into a cell array. Index with `varargin{i}` and use `length(varargin)` for the count. It is a MATLAB®-compatible programming function available in SimLab with the same calling syntax as MATLAB® — typically: function out = myfn(varargin).
Can I run varargin() in my browser?
Yes. Open SimLab at simulations4all.com/simlab, write or paste code that calls varargin(), and run it. This function’s calculation runs locally in the browser. SimLab session analytics, sharing, feedback, and eligible acceleration have separate network boundaries.
