insert for loop in the given script

Hi, I have this script working for LN = [1], I need to modify it to make it work for LN 1 to n. I was thinking of using a for loop.

%%%%%%%%% estraggo il LAYER numero:[single or multiple]
LN=[1];
%cerco in III colonna i calori di LN
for i=1:Nrow
        if isempty(WS{i,3})
       idx(i,2)=0;
       continue
        end
       if ismember(WS{i,3},LN)
           idx(i,2)=1;
       end
end

% %%Prendo solo i wall outer
% for i=1:Nrow
%     if isempty(WS{i,5})
%        idx(i,3)=0;
%        continue
%     end
% idx(i,3)=double(strcmp(WS{i,5},'WALL-OUTER')); 
% end

%%Prendo TUTTE le linee depositate
for i=1:Nrow
    if isempty(WS{i,5})
       idx(i,3)=0;
    else
     idx(i,3)=1;   
    end

end

%%prendo solo quelli con deposition ==1
for i=1:Nrow
    if isempty(WS{i,7})
       idx(i,4)=0;
       continue
    end
idx(i,4)=WS{i,7}; 
end

idx=prod(idx,2);
figure(1)
axis equal
for i=1:Nrow
    if idx(i)==0
        continue
    end
    X=[WS{i,1}(1),WS{i,2}(1)];
    Y=[WS{i,1}(2),WS{i,2}(2)];
    Z=[WS{i,1}(3),WS{i,2}(3)];
    plot3(X,Y,Z,'r');
    
        hold on
