Wavelet and hdl coder

Hi, I'm new to use the HDL coder.The val vector is sine with noise .My problem in fixed-point conversion :

function base=baseline(val)
n=10;
[e,f]=wavedec(val,n,'db6');   
for i=1:f(1);e(i)=0;               
end             
base=waverec(e,f,'db6');
end

Error:  
Expression must be numeric. Found it to be
  embedded.fi {ufix5}

Possible error? Thank you

You can check the documentation of wavedec and waverec and see if you passed in the right arguments.
