how to solve Index exceeds the number of array elements (1).

Hi guys, I'm writing a code for simulink model auto generation . But when i run code, it popup this error . How can i solve this problem.

Index exceeds the number of array elements (1).

Error in Create_topology (line 42)

hmp(k) = add_line(mdl,htp{k-1}.RConn(2),htp{k}.LConn(1),'autorouting','on');

open_system('Coil_Architecture');

mdl = 'Coil_Architecture/Coil';

h = find_system(mdl,'FindAll','on','Name','Coil');

Num_Turns = 100 ;

set(h,'Num_Turns',num2str(Num_Turns));

ht = zeros(Num_Turns,1);
hmp = zeros(Num_Turns,1);
htp = cell(Num_Turns,1);

for k = 1:Num_Turns
    
    nk = num2str(k);
    
    % add turn
    
    ht(k) = add_block('Unit_Turn/Turn_1', [mdl,'/Turn_',nk]);
    
    posc = get(ht(k),'Position');
    
    set(ht(k),'Position',posc + [0 30*(k-1) 0 30*(k-1)]);
    
    % get port handles
    
    htp{k} = get(ht(k),'PortHandles');
    
    
    
    % connect turn to turn
    
    
    
     if k > 1
         
         
         
     hmp(k) = add_line(mdl,htp{k-1}.RConn(2),htp{k}.LConn(1),'autorouting','on');   
         
            
     end
    
end

Hi,

could you also post your complete model: Coil_Architecture to simulate and find out more specific details of your err message?

Hi,

thanks for your answer .

i've already up loaded the whole model.

Answer 1

What this error is saying is that at some point in that line you are exceeding the number of elements in an array. The (1) is indicating that the actual number of elements in the array is 1.

My guess is that htp{k-1}.Rconn(2) may only have a length of 1.

If it is not that, right before the line display each of your variables and see that they are what you expect them to be.

Hope this helps

Hi David,

Thanks for your answer. I think the variable should be ok.

[David K.]

Sorry, I meant the .RConn(2) part. What does a single cell look like of htp?

[Sam]

.RConn(2) point only the connection port. This is how htp looks like. I've already uploaded the whole model , if you don't mind to look into it.

[David K.]

Just did so, appears the issue you mentioned is solved by changing

htp{k-1}.RConn(2)

to

htp{k-1}.RConn(1)

Since the struct appears that RConn and LConn are single variables and so there is no .RConn(2). I could not get it working since for me it now said the Turn_1 block could not be added but I expect that may just be my stuff for now. But the indexing issue is gone.

Thanks a lot bro! It worked! By the way you can delete the 2 Turn Blocks in the Coil SubSystem and run the m file again, it should work like the Pic below.
