Hello, what should i choose for f array if my y1=A and D1=b ( I want only for inequality ).

clc ; 
clear all ; 
close all ;
% % N = input('Tell me the length N: '  );
N = 25;
K = N + 1 ;
w = linspace( 0 , pi , 10*K);
w=w';
D1= ones( 2*length(w),1);
W1= ones( 2*length(w),1);
for i = 1:1:length(w)
    if w(i)>= 0.4*pi
        h = 2*i;
        break;
    end
end
for i = 2:2:length(w)
    D1(i)= -1;
end
for h = h:length(D1)
    D1(h)= 0;
    W1(h) = 2;
end
% for i = 2:2:2*length(w3)
%     W1(i)= -1*W1(i);
% end
y1 = zeros( length(D1) , K+1);
for i = 1:1:length(w)
    for j = 1:1:K+1
        y1(2*i-1,j) = 2*cos((j-1)*w(i));
        y1(2*i-1,1) = 1;
        y1(2*i,j) = -2*cos((j-1)*w(i));
        y1(2*i,1) = -1;
        y1(2*i-1,K+1) = 1/W1(2*i);
        y1(2*i,K+1) = -1/W1(2*i);
    end
end
D1 = D1';
f = ones( 1 , K+1);
% f(:,K+1)=1;
X = linprog(f,y1,D1)
Optimal solution found.
X = 27×1
