I am receiving the message "4x0 empty double matrix ". when the output is nul. I want it to be 0. when its empty

code line:

malicious=n_selfish_veh(n_selfish_veh(:,3) & n_selfish_veh(:,4) < time_ee ,:)

Do you mean you want to do something like this:

if( isempty(malicious) )
    malicious = 0;
end

can we do it without if condition such as , isnan(malacious)=0 but its not working properly
