Problem with a high pass filter

I would like to make a high pass filter so I have used fdatool for set up of it, which generated a function Hd, then I have imported everything to my source code but it doesn't work yet. I don't know why and can't to find and solve that problem.

function Hd = horni_propust_01
%HORNI_PROPUST_01 Returns a discrete-time filter object.

% Elliptic Highpass filter designed using FDESIGN.HIGHPASS.

% All frequency values are in Hz.
Fs = 48000;  % Sampling Frequency

N     = 10;    % Order
Fpass = 1000;  % Passband Frequency
Apass = 1;     % Passband Ripple (dB)
Astop = 80;    % Stopband Attenuation (dB)

% Construct an FDESIGN object and call its ELLIP method.
h  = fdesign.highpass('N,Fp,Ast,Ap', N, Fpass, Astop, Apass, Fs);
Hd = design(h, 'ellip');

[y,Fs,nBits]=wavread('def.wav'); 
left=y(:,1);                        % Left channel 
right=y(:,2);                       % Right channel
hd = horni_propust_01;
fr = filter(hd,right);
zvuk = left - fr;
player = audioplayer(zvuk,Fs,nBits);
play(player);

Please specify what you mean by "...I have imported everything to my source code but it doesn't work yet"

What error message are you seeing?

You should just be able to execute the following in the workspace to filter one channel of your .wav file.

   Fs = 48000;  % Sampling Frequency

   N     = 10;    % Order
   Fpass = 1000;  % Passband Frequency
   Apass = 1;     % Passband Ripple (dB)
   Astop = 80;    % Stopband Attenuation (dB)

   h  = fdesign.highpass('N,Fp,Ast,Ap', N, Fpass, Astop, Apass, Fs);
   Hd = design(h, 'ellip');
   [y,Fs,nBits]=wavread('def.wav'); 
   left=y(:,1);                        % Left channel 
   right=y(:,2);                       % Right channel
   fr = filter(Hd,right);

There is no error.. I just didn't know how to use this function to work my code. Now its okay. I try to filter a voice from song..

Could you please share how you did it pls. thank you :)
