Thanks

You can find the number of input arguments supported on the matlab version that you are using the example below: I was able to call a function with 100000 input arguments to test...

E.g. At the Command Prompt construct a test string of arguments...

s='';for n=1:100000,s=[s,' ',num2str(n)];end

Write a Function to be called...

function [varargout] = TestFunc(varargin)
    disp(['This function was called with ',num2str(nargin),' arguments']);
end

Test on Command Prompt

>> eval(['TestFunc ',s,';'])
This function was called with 100000 arguments

Ah... my answer was in terms of named variables; I was not considering varargin
