Hardlim

[Dimitri]

I guys.
I am newbe in octave an in this list. I have a question about use a Matlab Code 
in Octave. I have this code:

case 3,
   disp(sprintf('\n** PART III - CLONALG (The CLONal Selection ALGorithm) **'));
   v = cadeia(100,44,0,0,0);
   disp(sprintf('Available Demo Tasks:'));
   disp(sprintf('1) GA (GLOBAL SEARCH)'));
   disp(sprintf('2) CLONALG (MULTI-MODAL OPTIMIZATION)'));
   disp(sprintf('3) CHARACTER (KNOWLEDGE ACQUISITION)'));
   ga_cga = input('Type the desired demo number (1) ,(2) or (3): ');
   switch ga_cga,
..................

% Function CADEIA
function [ab,ag] = cadeia(n1,s1,n2,s2,bip)
if nargin == 2,
   n2 = n1; s2 = s1; bip = 1;
elseif nargin == 4,
   bip = 1;
end;
% Antibody (Ab) chains
ab = 2 .* rand(n1,s1) - 1;
if bip == 1,
   ab = hardlims(ab);
else,
   ab = hardlim(ab);
end;
% Antigen (Ag) chains
ag = 2 .* rand(n2,s2) - 1;
if bip == 1,
   ag = hardlims(ag);
else,
   ag = hardlim(ag);
end;
% End Function CADEIA

All before code is fine until line  v = cadeia(100,44,0,0,0); When run cadeia 
function:

Display this error:

** PART III - CLONALG (The CLONal Selection ALGorithm) **

Hardlim is supported for Octave?. Exist any replace order?.
