>> TourLength Not enough input arguments. Error in TourLength (line 3) n=numel(tour);

function L=TourLength(tour,model)

n=numel(tour);

tour=[tour tour(1)];

L=0;

for k=1:n

    L=L+model.d(i,j);
    
end

How can i solve it

Most probably you're trying to execute this as a Matlab script and not as a function. You need to properly call the function from command window or from the other script (or function) with specified arguments.

Hi Wonseh,

As per my understanding, you have created a function TourLength containing 2 input arguments. If you directly run this function in MATLAB by clicking the run button, you will encounter a similar error. For example, if executing from the command window you might need to enter the following command

TourLength(input_argument1, input_argument2); 

Also, you might need to ensure that the arguments passed as the function parameters are appropriate. Inappropriate arguments can also lead to numel error.
