title: Too many input arguments in MATLAB
body: <p>When I run the following code:</p>
  
  <pre><code>xdata2 = [1 3 4 5];
  ydata2 = [3 9 76 73];
  params = [0.1 0.5 0.0 -0.5 0.2 0.8];
  y = svenssontest2(xdata2,ydata2,params,0.636,1.9632);
  </code></pre>
  
  <p>I get the error message "Too many input arguments", but the number of input arguments is correct. Here's the code for the function <code>svenssontest2</code>:</p>
  
  <pre><code>function [alpha L1 L2] = svenssontest2(tau,Y,params,L1,L2)
  
  tau=tau.';
  Y=Y.';
  
  nObs=length(Y);
  
  %z=1;
  
  %for(j =1:50)
  
      %L2=j/200+0.01;
  
      %for(k=1:50)
  
       %   L1=k/200+0.01;
  
          Lev1= [params(1)*ones(nObs,1) params(2)*(1-exp(-params(5).*tau))./(params(5).*tau) params(3)*((1-exp(-params(5).*tau))./(params(5).*tau)-exp(-params(5).*tau)) params(4)*((1-exp(-params(6).*tau))./(params(6).*tau)-exp(-params(6).*tau))];
  
          Y=Y-Lev1;
  
          G= [ones(nObs,1) (1-exp(-L1.*tau))./(L1.*tau) (1-exp(-L1.*tau))./(L1.*tau)-exp(-L1.*tau) (1-exp(-L2.*tau))./(L2.*tau)-exp(-L2.*tau)];
  
          alpha =G\Y;
          u=Y-G*alpha
          stderr=sqrt(diag((u'*u)/(length(Y)-4)*pinv(G'*G)));
          Sum_u2 = sum(u.^2);
          Res(1,:) = [Sum_u2 alpha' L1 L2];
      %   z=z+1;
  
     % end
