Undefined function 'shortestPath' for input arguments of type 'double'.

Every time i use

>> [ending_pts ind] = solveTSP( ending_pts, true );

an error message appears:

Undefined function 'shortestPath' for input arguments of type 'double'.line 20

here is the code that give the message error:

% plot the shortest path

     xd=[];yd=[];
for i = 1:(N_cities+1)
    xd(i)=ending_pts(shortestPath(i),1);
    yd(i)=ending_pts(shortestPath(i),2);
end
line(xd,yd);
title(['Path length = ',num2str(shortestPathLength)]);
hold off;

Any suggestions?

Thanks!

You don't have the matrix (I assume) shortestPath or N_cities defined anywhere in your code. So it's either a global variable or you just missed it.

In this case, I'm assuming that shortestPath is a matrix containing the shortest distances between the cities.
