resample input argument not sufficient

Dear Team, the resample function leads to an error "Not enough input arguments." Error in sinc (line 6) for k=1:N Error in firls (line 169) b = b + (F(s+1)*(m*F(s+1)+b1)*sinc(2*k*F(s+1)) ... Error in resample>uniformResample (line 208) h = firls( L-1, [0 2*fc 2*fc 1], [1 1 0 0]).*kaiser(L,bta)' ; Error in resample (line 104) [varargout{1:max(1,nargout)}] = uniformResample(varargin{:}); This already happens when I call the example from the help browser (Version 2016a) fs = 10; t1 = 0:1/fs:1; x = t1; y = resample(x,3,2); What can I Change?
