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.
