Hi, Can I know how to make this algorithm to become function in matlab because I want to use fmincon in matlab to find minimum J

f=[];
abs_H=[];
t=[rand(101,2)];
for x=1:101;   % number of  frequency
    for y=1:n; %number of t
        Fr(x,y)=cos(2*pi*f(x)*t(y)); %real number of F
        Fi(x,y)=-i*sin(2*pi*f(x)*t(y)); % imaginary number of F
    end 
end
   Fr_T=Fr';
   Fi_T=Fi';
   A=(Fr_T*Fr)+(Fi_T*Fi);
   B=(Fr_T*fr)+(Fi_T*fi);
   a=lsqminnorm(A,B) ;    % solve tp get a set of a
J(z)=sum((a-abs_H))^2; % to find the minimum of J from measured data
 end
J_min=min(J);
