%% Errror description Even though I tried to solve it by assigning variable Y to a temporary variable, it didn't work?
%% The entire array or structure Y-temp is broadcast variable. This might result in unneccesary comunicaiton overhead?
for k=0:1:(M-1)
    z_plane_path(k+1)=A*W^(-k);
end
ChirpZ_outY(1:M)=0;
Y_temp=Y(:,1);
parfor k=0:M-1
    sum1=0;
    
    for n=0:N-1
        sum1=sum1+(Y_temp(n+1)*z_plane_path(k+1)^(-n));
    end
ChirpZ_outY(k+1)=sum1;
end
DFT_SS_Eq_out=ChirpZ_outY/N*2;
disp(i);
end
