Error about "plotfdesign": Expected a string for the parameter name, instead the input type was 'double'.

Hi, I was using the function plotfdesign and using the example in that file but error appears:

  g= repmat(fullfact([2 2]),100,1); 
  g1= find(g(:,1)==1); 
  g2= find(g(:,1)==2); 
  x= zeros(size(g,1),1); 
  x(g1)= normrnd(10,1,numel(g1),1); 
  x(g2)= normrnd(5,3,numel(g2),1);
H= plotfdesign(x,g);

Error appeared:

Error using notBoxPlot (line 218) 
Expected a string for the parameter name, instead the input type was 'double'. 
Error in plotfdesign (line 153) 
  H= notBoxPlot(yy,x(unique(g(rows,1))),0.7*bs,'sdline');

I’m using R2016a. Other people using this function very well, but I do not know what’s wrong with my computer.

I put the two lines into try-end block, and it works now, but I still do not know if this will cause unforeseeable problems.

plotfdesign (line 162) try set([H(k).sd], 'Color',0.75*cmap(k,:),'LineWidth',2); end

notBoxPlot (line 218) try params.parse(varargin{:}); end
