title: Failure in initial user-supplied objective function evaluation. FSOLVE cannot continue
body: <p>I am trying to solve a large set of non-linear equation using fsolve in MATLAB 2013. When I run this code:</p>
  
  <pre><code>Unkn0=zeros(3249,1); % Guess
  [Unkn,feval,exitflag,output]=fsolve(Eqnh,Unkn0);
  </code></pre>
  
  <p>Here Eqnh is a function handle for 3249 variables and 3249 equations.
  I get the following error:</p>
  
  <pre><code>Error using
  Not enough input arguments.
  Error in fsolve (line 218)
              fuser = feval(funfcn{3},x,varargin{:});
  Caused by:
      Failure in initial user-supplied objective function evaluation. FSOLVE cannot continue. 
  </code></pre>
  
  <p>I can provide Eqnh written in a text file if there is any need of it.</p>
